Lip cancer is a malignant neoplasm that consists of elements of the integumentary epithelium of the red border of the lips. A tumor on the upper lip appears rarely. Over time, lip cancer spreads to the bones of the lower jaw. Atypical cells are transported with lymph to the lymph nodes, resulting in the appearance of new malignant foci.
Doctors at the Yusupov Hospital carry out early diagnosis of lip cancer using modern research methods. Oncologists provide radiation therapy and perform gentle surgical interventions. In the later stages of lip cancer, complex therapy is used. Early diagnosis of a malignant lip tumor and adequate therapy can not only save the patient’s life, but also avoid cosmetic defects after surgery.
Lip cancer - what is it?
Depending on the type of tumor growth, the following forms of lip cancer are distinguished:
- Papillary;
- warty;
- Ulcerative;
- Ulcerative-infiltrative.
A malignant tumor of the lip in 95% of cases is represented by keratinizing squamous cell carcinoma. In 5% of cases, histologists have squamous cell non-keratinizing cancer of the lip mucosa. A tumor of the lip, which from the inside, on the mucous membrane, is characterized by a malignant course (infiltrative growth and early metastasis to regional lymph nodes).
A tumor of the lower lip most often affects the border of the lower lip. A crack, ulcer or swelling forms on it, which looks like a wart. The disease is predominantly diagnosed in people over 60 years of age.
Cancer of the upper lip occurs less frequently than the lower lip, but the tumor is more aggressive. Upper lip cancer has a high risk of metastasis and spreads quickly. This is explained by the fact that the malignant tumor is located close to the nasal cavity, where the blood supply system is developed. A tumor on the inside of the lip is dangerous because it quickly grows into the soft tissue.
Melanoma on the lip is 10 times less common than squamous cell carcinoma of the lip, but is characterized by a high degree of malignancy. Basically, the tumor is located on the red border of the lower lip. It penetrates deeply into tissues, quickly transfers to nearby tissues and gives metastases.
At the Yusupov Hospital, oncologists make a diagnosis of lip cancer using the following methods:
- Examination with the naked eye and using stomatoscopy;
- Cytological examination of impression smears from a tumor ulcer;
- Histological examination of lymph node punctate.
After establishing the primary diagnosis, a comprehensive examination of the patient is carried out.
Prognostic factors
Prognosis (outcome) factors for lip cancer are:
- prevalence of the process (size of the primary tumor, presence of metastases);
- clinical and anatomical form of cancer growth (exophytic forms proceed more favorably);
- morphological type of cancer (the non-keratinizing type is more aggressive);
- nature of tumor growth (primary or recurrent);
- age (patients under 40 years of age have a more malignant course).
The prognosis for lip cancer is generally favorable.
A worsening prognosis is associated with locally widespread infiltrative growth and significant regional and distant metastasis.
Causes of lip cancer
Lip cancer develops for many reasons:
- From smoking;
- After a long stay in the sun;
- As a result of inflammatory processes of an infectious and non-infectious nature;
- Under the influence of high temperatures;
- In the presence of microtraumas;
- Due to prolonged exposure to chemicals.
Lip cancer often develops from smoking. Men get lip cancer much more often than women. Currently, the trend is changing, because many women suffer from tobacco addiction. Doctors believe that lip cancer develops due to smoking strong cigarettes for a long time.
The average smoker smokes at least ten cigarettes a day. In this case, the paper surface is constantly in contact with the lips. The skin here is especially delicate and sensitive. Microcracks appear on its surface. They are invisible to others and do not cause problems for the smoker. Damaged areas of the epithelium are affected by tobacco smoke. It contains a lot of harmful substances. Skin cells begin to degenerate.
The cause of mechanical trauma that causes lip cancer can be improperly made dentures, the habit of holding various objects with the lips (nails, the mouthpiece of a smoking pipe), or biting the lower lip. The mechanism of development of lip cancer is as follows: a long-term non-healing crack, wound, inflammation on the lip, papilloma develops into leukoplakia, Manganotti cheilitis, keratoacanthoma, warty form of dyskeratosis or other precancerous diseases. Against this background, lip cancer occurs.
Precancerous diseases of the lips
Lip cancer does not occur on healthy mucous membranes. Malignant neoplasms develop against the background of obligate or facultative precancerous diseases. Obligate precancerous diseases include:
- Abrasive precancerous cheilitis Manganotti;
- Warty precancer of the red border;
- Limited precancerous hyperkeratosis of the red border.
Facultative precancerous diseases with greater potential for malignancy are:
- Erosive and verrucous leukoplakia of the lip;
- Papilloma;
- Keratoacanthoma;
- Cutaneous horn.
Malignant neoplasms of the lip can develop against the background of optional precancerous diseases with less potential malignancy:
- Flat leukoplakia of the lip;
- Chronic ulcers;
- Ulcerative and hyperkeratotic forms of lupus erythematosus and lichen planus;
- Chronic cracked lips;
- Post-X-ray cheilitis;
- Meteorological and actinic cheilitis.
Background conditions that are precursors to lip cancer include scars after burns, trauma, surgery, and benign neoplasms.
Heilith Manganotti
Abrasive precancerous Manganotti cheilitis occurs in older people. Small, round erosions appear on the lips, which do not heal for a long time. They have a smooth surface of yellow-red or bright red color. In some cases, a bloody or serous crust appears on the surfaces of erosions. If you remove it, the opened wound bleeds a little. Touching erosions does not cause pain. Once erosion appears, it does not heal for several weeks or months. After disappearing, soon enough new erosions appear in their place or nearby.
Manganotti cheilitis is diagnosed by external examination and questioning of the patient. This disease has symptoms similar to those of herpes, leukoplakia, lichen planus or lupus erythematosus. For differential diagnosis, oncologists scrape the affected area of the lip and send it for a thorough histological examination. This scraping makes it possible to detect emerging cancer cells in a timely manner and prevent the development of a malignant neoplasm of the lip.
Leukoplakia and lip hyperkeratosis
Leukoplakia of the lip is a lesion of the mucous membranes with keratinization of the epithelial tissues. Unfavorable factors that contribute to the development of leukoplakia may be alcohol abuse, smoking and eating very spicy foods. Leukoplakias of the lower lip most often develop in the mucous membranes at the corners of the mouth.
Hyperkeratosis of the lips appears as a limited area from 0.2 to 1 cm in diameter. Its surface is smooth, covered with thin, tightly packed grayish-white scales. Scraping cannot remove them.
Symptoms of lip cancer
There are local and general signs of lip cancer. Local symptoms of a malignant neoplasm can often be seen on the lower lip. When the pathological process is located on the mucous membrane of the lips, facing the vestibule of the mouth, the tumor has a pronounced malignancy. General signs of lip cancer can develop if the tumor is not detected in a timely manner and treated inadequately in the later stages of cancer.
First symptoms
The first signs of lip cancer usually go unnoticed. First, you can determine the enlargement of the mental lymph nodes. You can notice this by feeling the lower jaw. The next early sign of lip cancer is a swelling of a dense consistency. Itching occurs in it. This neoplasm is usually mistaken for a herpetic rash.
A small ulcer with a crust forms in the center of the swelling, which does not cause pain. If it is removed, the patient feels quite severe pain, and upon closer inspection, he may find a bleeding base, which is formed by tubercles.
Local signs of tumor
Symptoms of lip cancer are:
- Dyskeratosis of the lips;
- Papilloma;
- Erosion;
- Cheilitis.
In most cases, dyskateriosis looks like cracks and ulcers. The erosions are covered with a crust and resemble herpes in appearance, but, unlike it, they do not heal after a certain period of time. Some patients have no ulcers or erosions. Instead, a small compaction appears, which over time grows and becomes covered with a crust.
On the red border of the lower lip, away from the midline, a patch or formation may appear that protrudes above the surface. An erosion or ulcer with a granular surface and a roll-like edge forms in the center of the tumor. The formation has a dense consistency and gradually increases in size, eventually acquiring an irregular shape. Its boundaries are unclear.
Exophytic lip cancer predominantly develops from a warty form of productive diffuse dyskeratosis of papilloma. With exophytic growth, the tumor has a dense consistency, often covered with flat scales. Endophytic growth of a cancerous tumor is characterized by the formation of an ulcer with uneven, dense edges. It often appears against the background of destructive dyskeratosis, quickly infiltrates the soft tissues of the lip and is prone to metastasis.
Symptoms of the disease should be a signal to immediately contact oncologists at the Yusupov Hospital. Lip cancer, treatment of which is started on time, is completely cured in 90% of cases.
Clinical picture
Symptoms of lip cancer are varied and are determined by previous precancerous diseases and the morphological type of tumor.
In the early stages, a small roller-like rim appears around the edges around the compaction or erosion, which indicates a malignant process.
Papilloma, cutaneous horn, focus of verrucous leukoplakia, warty or nodular precancer develop into exophytic forms of cancer. The process lasts a long time, the infiltration of the underlying tissues increases gradually.
Destructive forms of dyskeratosis, Mangannotti cheilitis, and other ulcerative processes develop into endophytic forms of cancer - ulcerative and ulcerative-infiltrative.
In later stages, the boundaries between the clinical and anatomical forms of cancer are blurred. If untreated, the bottom of the ulcer reaches the muscle layer, tumor infiltration spreads to the entire lip, chin tissue, floor of the mouth, cheeks, and lower jaw.
Tissue breakdown intensifies, secondary infection occurs, nutrition is disrupted, and exhaustion develops.
Lip cancer is characterized by lymphogenous metastasis.
Metastases can develop on both sides (25%). Metastasis of cancer of the lower lip at stage I is observed in 2-6% of cases, at stage II - in 15-20%, at stage III - in 35% and at stage IV - in 70% of cases.
Distant metastases of lower lip cancer are rare (2%), mainly to the lungs.
Cancer of the upper lip, as a rule, is more malignant due to the characteristics of lymph circulation and metastasis.
Stages
Currently, the generally accepted classification of lip cancer is TNM (T-size of the tumor, N-damage to the lymph nodes, M-metastases). Based on the size of the tumor, there are 4 stages of lip cancer.
Table 1. Stages of lip cancer
Stage | Tumor size |
T1 | Less than or equal to 2cm |
T2 | More than 2-4cm |
T3 | More than 4cm |
T4a | The tumor grows into the cortical layer of the bone, tongue muscles, maxillary sinus and skin |
Т4в | The tumor grows in the bed of the masseter muscle, the pterygoid process, the internal carotid artery and the base of the skull |
If on the affected side there are single enlarged lymph nodes, the size of which is less than 3 cm, this is stage N1 lip cancer. At stage N2, enlarged lymph nodes are detected on the affected side, the diameter of which is more than 3 cm. If the patient has single enlarged lymph nodes on the affected side measuring 3-6 cm in size, this is stage N2a of lip cancer. At stage N2, oncologists determine multiple metastases to the lymph nodes. Their size is equal to or greater than 6cm. In the presence of bilateral metastases in the lymph nodes measuring 6 centimeters, they speak of the N2c stage of lip cancer. If the diameter of the lymph nodes exceeds 6 cm, this is stage N3 of the disease.
In the absence of distant metastases, oncologists determine stage M0 of lip cancer, if there are distant metastases - M1, in the case of distant metastases that cannot be assessed - MX. The diagnosis of “early stage lip cancer” is made in the presence of a tumor less than or equal to 2 cm, the presence of single enlarged lymph nodes less than 3 cm on the affected side and the absence of distant metastases. This is T1 N1 M0.
Prognosis and survival
It is difficult to make a prognosis for oncology, but as for lip tumors, the prognosis is conditionally considered favorable.
If the pathological process is at the initial stage of development (stage 1-2): | The survival rate for patients is good and ranges from 97-100%. |
If cancer develops and metastases appear: | The survival rate decreases and is about 85% if the tumor can be surgically removed. |
In severe condition, when the cancer reaches stage 4: | The survival rate of patients decreases and amounts to 55%. |
Much depends on the individual characteristics of the body. But lip tumors develop slowly, and the survival rate decreases when metastases appear. They destroy lymph nodes and jaw bones.
If you consult a doctor in a timely manner, such complications can be avoided.
Diagnosis of a tumor by a doctor in a hospital
What does lip cancer look like? It could be a small ulcer or a widespread tumor. Doctors at the Oncology Clinic of the Yusupov Hospital make a diagnosis of lip cancer based on the patient’s complaints, the results of an external examination and additional studies. The oncologist carefully examines and palpates the lips, cheeks, gums and regional lymph nodes. When examining the red border of the lips, skin and mucous membrane, use a magnifying glass.
How to identify lip cancer? Further examination is carried out using instrumental and laboratory diagnostic methods:
- Ultrasound examination;
- X-rays of the lower jaw;
- Panoramic tomography;
- Cytological examination of material obtained by taking fingerprint smears from the surface of the ulcer or histological examination of tissue obtained during a biopsy.
For lip cancer with lymphatic metastasis, a biopsy of the lymph nodes is performed. To exclude hematogenous metastases, chest X-ray and ultrasound examination of the abdominal organs are used. When the diagnosis of lip cancer is confirmed, an X-ray examination of the chest organs, general clinical and laboratory examination (electrocardiography, blood and urine tests) are performed.
A PET-CT study (positron emission computed tomography) is prescribed for the following purposes:
- Determining the stage of lip cancer;
- Assessment of response to treatment;
- Detection of disease relapse during the observation period.
PET-CT is an innovative method that combines the capabilities of computer technology and radiology. At the Yusupov Hospital, it is used not only to diagnose lip cancer, but also to monitor tumor development and evaluate the outcome of treatment. Thanks to PET-CT, radiologists have the opportunity to very accurately carry out radiation treatment, significantly reduce the irradiation area, and minimize the impact on healthy organs and tissues.
In many cases, the use of PET-CT excludes a number of additional studies in the future. This allows patients of the Yusupov Hospital to save time and money. The issue of the need to use this method is decided individually for a specific patient at a meeting of the expert council with the participation of professors and doctors of the highest category. A comprehensive examination of patients using the latest diagnostic equipment, the use of modern methods of performing laboratory tests using high-quality reagents allows oncologists at the Yusupov Hospital to obtain reliable results and provide adequate therapy for lip cancer at an early stage.
Diet
Diet during radiation therapy
- Efficacy: no data

- Groceries cost: 2300 - 3800 per week
Diet for cancer
- Efficacy: no data
- Duration: until recovery or lifelong
- Groceries cost: 2500 - 4800 per week
During the treatment of the disease, it is necessary to follow the doctor's advice regarding nutrition. It is important to practice gentle nutrition: it is recommended to eat dishes warm, preferring soft and easily digestible foods.
- It is important to avoid hot drinks, broths, and soups.
- Alcoholic drinks should be excluded.
- It is also not recommended to eat spicy, fried, smoked foods.
- It is necessary to reduce sweets and dairy products to a minimum.
The diet should consist of boiled vegetables, boiled meat, fermented milk dishes, and cereals. Drinking should be plentiful.
Treatment of lip cancer
How to treat lip cancer? When treating the disease, oncologists at the Yusupov Hospital take into account many different factors: the patient’s age, histological type of tumor, features of the spread of the tumor. Doctors at the Oncology Clinic provide multidisciplinary treatment for lip cancer:
- Surgical interventions;
- Radiotherapy;
- Chemotherapy.
Regardless of the chosen technique, they affect the lesion or tumor, areas of regional metastasis. For grades I and II of lip cancer, radiation treatment is performed, which includes external radiotherapy and surgery.
Treatment in the initial stages
Squamous cell carcinoma of the lower lip is a common complex tumor process. Its treatment consists of two stages: removal of the main focus and the fight against metastases that have spread to neighboring tissues and organs. Radiation treatment can suppress the development of a tumor focus. The radiologist selects the method of radiation therapy individually, depending on the size of the tumor, stage of the disease, and age of the patient.
Removal using the Krail method
In the initial stage of the tumor, surgeons perform a wedge-shaped excision of the entire thickness of the lip under local anesthesia. In order to remove a defect on the lip, plastic surgery is performed - skin flaps are transferred from the patient's cheek. Removal of the lesion is performed using the Krail technique. The operation is performed at the first and second stages of lip cancer, when the tumor has not spread to nearby tissues. Surgical excision of carcinoma makes sense in the absence of metastases.
The decision to remove a lymph node is made by an oncologist surgeon if the primary tumor process has already been cured or if the lymph node is removed along with the removal of the main lesion. In some cases, surgeons remove the primary cancerous tumor, the affected lymph nodes and the vessels that connect them. The scope of the operation is determined collectively by the clinic's oncologists.
Due to the fact that metastasis can occur in a cross way, the lymphatic apparatus of the suprahyoid region on the left and right is removed. If the oncologist sees that there are cancer metastases in certain lymph nodes, he decides to remove them, and those that are located along the lymph outflow.
Treatment tactics for lip cancer depend on the stage of the disease:
- Preventive surgery at stages I and II of lip cancer is carried out exclusively in cases where it is not possible to control the dynamics of the disease and there are unfavorable prognoses regarding the spread of cancer;
- At stage III, in the absence of metastases, treatment is carried out using a combined effect on the lesion and adjacent areas;
- In case of spread of cancer cells and the presence of single metastases in the lymph nodes, oncologists at the Yusupov Hospital perform combined treatment of lip cancer with subsequent surgery, plastic surgery and surgical correction of the lips;
- In stage IVC, palliative chemoradiotherapy is performed.
Candidates and doctors of medical sciences use innovative methods of treating lip cancer. The presence of modern equipment and competent medical personnel who are attentive to all the wishes of patients allows us to achieve good results in the treatment of lip cancer for many years. Lip cancer, treated in the early stages, is cured in 97-100% of cases. At stage III, 67-80% of patients can be cured. In the fourth stage of cancer and repeated relapses, complete recovery occurs in 55% of cases.

For persons prone to dyskeratosis of the lips and cheilitis, oncologists at the Yusupov Hospital conduct an annual preventive examination. Secondary prevention of lip cancer consists of regular dental treatment at the dentist, surgical intervention in the presence of dyskeratosis and cheilitis.
Pathogenesis
The spread of the oncological process on the lower lip is due to its anatomical and physiological characteristics, as well as its injury to teeth affected by caries and exposure to carcinogens.
The condition, which is defined as obligate precancer, includes papillomas and focal dyskeratoses . In addition, malignant transformation can occur in diffuse dyskeratosis and keratoacanthoma .
