Cancer is categorized from stage 0 to stage 4 depending on the extent of spread and the size of the tumor. After determining the stage of cancer, an appropriate treatment method is planned for the patient. Additionally, the patient is informed about what needs to be done before and after treatment.
Treatment methods include radiotherapy (radiation therapy for cancer), chemotherapy (drug therapy for cancer), surgery, immunotherapy (supporting the immune system for recovery), and specific drug therapy. If you are experiencing symptoms of lip cancer, you should definitely consult an ear, nose, and throat specialist.
What is Lip Cancer?
Lip cancer is oral cancer that occurs on the lower or upper lip, starting with abnormalities in the deoxyribonucleic acid (DNA) of a lip cell. The deterioration in DNA leads to abnormal growth and division of lip cells, resulting in the emergence of a tumor or a group of abnormal cells. There are four different types of cancer that can affect the lips: squamous cell carcinoma, melanoma, lymphoma, and small salivary gland cancers. It is also more frequently seen in patients who are highly exposed to sunlight.
What Are the Types of Lip Cancer?
1. Squamous Cell Carcinoma
This is the most common type of lip cancer. It is characterized by abnormal cell division resulting from a deterioration in the DNA of the squamous cells that cover the lips (the cells that cover the outer surface of the lip).
2. Melanoma
Melanocytes, which are pigment-producing cells, are found in the mucosal areas of the lips or mouth. The cancer type originating from these cells is called melanoma.
3. Lymphoma
Lymphoma, which originates from lymphocytes (immune system cells), can rarely occur in the oral cavity and can affect the lips from there.
4. Small Salivary Gland Cancers
These cancers affect the salivary glands and can indirectly spread to the lips.
What Are the Symptoms of Lip Cancer?
Symptoms of lip cancer are often observed as sores and pigment changes on the lips in pictures. In the early stage, it may only appear as a slight bump or a flat color change. Other symptoms include:
- An open sore or lesion on the lip that does not heal
- Pain, bleeding, and numbness in the lip area
- Red and white spots on the lip
- Itchy sores and scaling on the lip
- Lump or thickening in the lip area
What Factors Affect the Development of Lip Cancer?
There are no definitive factors that cause cancer in the lips, but there are conditions that increase the risk of developing it. Factors that can lead to tumor formation in lip cells include:
- Excessive sun exposure: The likelihood of tumor development is higher on the lower lip due to greater exposure to sunlight. It has been observed that individuals who spend more time outdoors are at a higher risk.
- Tobacco and alcohol use: Cigarettes contain carcinogenic substances, which stimulate abnormal cell division. Alcohol damages the DNA and proteins of cells in the lip and mouth area.
- Age and gender: Lip cancer frequently occurs in men over 40 years old.
- Immunodeficiency, individuals with HIV and HPV viruses: These factors increase the likelihood of developing lip cancer.
- Frequent injuries to the lips: Injuries caused by toothpicks, pens, or biting the lip can lead to cancer.
- Poor diet lacking fruits and vegetables: This leads to a deficiency in vitamins and minerals, which can trigger cancer formation.
What Is the Importance of Early Diagnosis in Lip Cancer?
Tumors developing in the lips are not as deadly as other cancers, but recognizing cancer in its late stages can lead to its spread to tissues near the lips and increase the size of the tumor. This situation complicates the treatment plan and reduces the chances of success in treatment. It also prolongs the recovery time after treatment. Therefore, if there is any suspicion, a specialist should be consulted.
How Many Stages Are There in Lip Cancer?
When consulting a specialist doctor, after detecting cancer in the lip cells, the area where the cancer is located is examined using magnetic resonance imaging (a method of imaging organs and tissues using magnetic waves) or tomography (an imaging technique using X-rays). The doctor determines the stage of cancer based on the results of this evaluation. These stages are classified into five categories by the American Joint Committee on Cancer (AJCC). These classifications consider the size of the tumor and how much it has spread. They are:
- Stage 0: Cancer is limited to the upper part of the lip cells.
- Stage 1: This is the early stage of cancer. The tumor is smaller than 2 centimeters and has not spread to deeper tissues.
- Stage 2: The size of the lip tumor is between 2-4 centimeters. It has not spread to local lymph nodes.
- Stage 3: This is the advanced stage of cancer. The tumor is larger than 4 centimeters and has spread to lymph nodes.
- Stage 4: In this stage, the cancer has spread to the jaw, the bone in the mouth area, the skin, and the lymph nodes in the neck.
What Are the Treatment Methods for Lip Cancer?
The treatment to be applied varies depending on the patient’s age, health status, size and location of the tumor, and the stage of cancer. Possible treatment methods include:
- Surgery: It can be applied to remove lesions on the lip and restore the old appearance. It is also used to remove tumors that have spread to lymph nodes in the neck area.
- Radiation Therapy: This is a treatment method using a source of radiation to destroy cancer cells. The radiation beam stops the division and growth of cancerous cells in the lip area, either near the lip or from an external machine.
- Chemotherapy: This is a drug treatment applied to kill cancer cells and relieve symptoms. It is often used in conjunction with radiotherapy for greater effectiveness.
- Immunotherapy: This is a drug treatment that supports the immune system to prevent the progression of cancer.
- Targeted drug therapy: This is a drug treatment that focuses on the genes and proteins of cancer cells. It aims to kill cancer cells by targeting these factors and is often used in conjunction with chemotherapy.
What Is the Process After Lip Cancer Treatment?
After treatment for lip cancer, there is a high likelihood of recurrence. Therefore, at this stage, tests used for cancer diagnosis are employed to check for recurrence. These tests are also referred to as follow-up tests after treatment. They can also be used to assess the success of the treatment.
To prevent emotional changes caused by cancer after treatment, the individual should be supported by their loved ones. The patient should not feel alone.
If you are experiencing symptoms of lip cancer, you should definitely consult a specialist. Information should be obtained about what needs to be done before and after treatment. During these processes, the individual’s relatives should provide psychological support as much as possible.
Frequently Asked Questions About Lip Cancer
How does lip cancer manifest?
An individual may suspect cancer by looking at photos of lip cancer and thinking they have similar sores on their lips, but a definitive diagnosis is made by consulting a specialist. After a physical examination, the doctor takes a tissue sample for biopsy (the process of taking tissue, cells, and fluid from the body for examination). The presence of cancerous cells in this tissue is evaluated. A biopsy is sufficient for diagnosis. Additionally, imaging tests are used to determine how far it has spread.
Is lip cancer dangerous?
Lip cancer is not as deadly as other types of cancer. Because it develops on a surface that can be easily seen, it can be identified and treated in the early stages.
Is there treatment for lip cancer?
There are treatment options that vary depending on the size, location, age, health status, and stage of cancer of the tumor. Treatment methods that can be used include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted drug therapy.
What happens if lip cancer is not treated?
If lip cancer is not treated in stages 0, 1, 2, and 3, it can progress to stage 4. In this stage, the tumor can spread to the oral cavity, lymph nodes, and neck area. It can also spread to the bone in the mouth area. This situation reduces the survival rate.
Does lip cancer spread?
Lip cancer does not spread to nearby tissues and lymph nodes in stages 0, 1, and 2. However, in advanced stages 3 and 4, it does spread to lymph nodes.
Which doctor treats lip cancer?
For non-healing sores and bleeding on the lips, it is necessary to see an ear, nose, and throat specialist. When the doctor suspects cancer, they can confirm the diagnosis through biopsy.
Is lip cancer contagious?
Cancer is not transmitted from person to person through close contact. A cancerous cell from one person does not survive in another person’s body because the immune system recognizes different cell types and removes them from the body.
Does smoking cause lip cancer?
Chemicals that cause cancer in lip cells are present in cigarettes. The likelihood of cancer development increases, especially due to increased exposure of the lips to cigarette smoke.
What do sores on the lip indicate?
Sores on the lip can include cold sores, dryness, peeling, scabbing, cracking, and wounds. These conditions are usually temporary. However, if these conditions persist for a long time, they may indicate cancer.
How does lip cancer go away?
Lip cancer can be quickly eradicated with appropriate treatment methods. Recovery is achieved through radiation therapy, surgery, chemotherapy, and immunotherapy methods.
How long does lip cancer surgery take?
The duration of surgery varies depending on the surgical method applied and the treatments used alongside it.
What are the symptoms of lower lip cancer?
Lip cancer can occur on the lower or upper lip, but it frequently develops on the lower lip. The general symptoms observed do not change. Symptoms include lumps, sores, bleeding, swelling, scabbing, color changes, and pain in the lip.
