What is head and neck cancer?
Head and neck cancer is a term for cancers that start in the head and neck region, including the mouth, nose, sinuses, salivary glands, throat, and voice box (larynx). Most head and neck cancers are squamous cell cancers, which begin in the moist tissues that line the head and neck. As the cancer grows, the cancer cells may spread into deeper tissue.
What are the symptoms of head and neck cancer?
● A lump in the neck
● A sore in the mouth or throat that does not heal and may be painful
● A sore throat that does not go away
● Difficulty in swallowing
● A change or hoarseness in the voice
● A red or white patch on the gums, tongue, lining of the mouth, unusual bleeding or pain in the mouth
What causes cancers of head and neck?
● Alcohol and tobacco use
● Infection with cancer-causing types of human papillomavirus (HPV), especially HPV type 16
● Paan (betel quid)
● Occupational exposure
● Radiation exposure
● Epstein-Barr virus infection
● Ancestry
● Underlying genetic disorders
What are the symptoms of specific regions where head and neck cancers occur?
● Oral Cavity: Look out for white or red patches on the gums, tongue, or mouth lining; growths or swelling in the jaw that may cause dentures to fit poorly or become uncomfortable; and any unusual bleeding or persistent pain in the mouth.
● Throat (Pharynx): Symptoms include pain when swallowing, persistent pain in the neck or throat, ringing in the ears, or difficulty hearing.
● Voice Box (Larynx): Signs to watch for include difficulty breathing or speaking, pain when swallowing, or ear pain.
● Paranasal Sinuses and Nasal Cavity: Be aware of blocked sinuses that don’t clear, chronic sinus infections resistant to antibiotics, nosebleeds, frequent headaches, swelling or issues with the eyes, upper teeth pain, or problems with dentures.
● Salivary Glands: Symptoms include swelling under the chin or around the jawbone, numbness or paralysis of facial muscles, or persistent pain in the face, chin, or neck.
How common are head and neck cancers in India?
Head and neck cancer is relatively common in India, accounting for about 30% of all cancers in the country. India has one of the highest rates of head and neck cancers globally, largely due to the widespread use of tobacco products, including chewing tobacco, and the consumption of alcohol.
Oral cancer, a subset of head and neck cancer, is particularly prevalent and is one of the most common cancers among Indian men. Factors such as poor oral hygiene, human papillomavirus (HPV) infection, and dietary habits also contribute to the high incidence rates. Early detection and prevention efforts are crucial in combating the high burden of this disease in India.
How can I reduce my risk of developing head and neck cancers?
Reducing your risk of developing head and neck cancers involves adopting several preventive measures:
1. Avoid Tobacco: Refrain from smoking or using smokeless tobacco products, as tobacco use is the leading cause of head and neck cancers.
2. Limit Alcohol Consumption: Excessive alcohol consumption increases the risk, especially when combined with tobacco use.
3. Practice Good Oral Hygiene: Regular brushing, flossing, and dental check-ups can help prevent conditions that may lead to oral cancers.
4. Protect Against HPV: Human papillomavirus (HPV) is linked to certain head and neck cancers, particularly in the throat. Vaccination against HPV and practicing safe sex can reduce this risk.
5. Maintain a Healthy Diet: A diet rich in fruits and vegetables can help lower the risk of cancer. Avoid excessive consumption of processed and red meats.
6. Limit Sun Exposure: Prolonged exposure to the sun without protection increases the risk of lip cancer. Use sunscreen and wear protective clothing, including hats.
7. Avoid Exposure to Harmful Chemicals: If you work in an environment with exposure to harmful chemicals, use appropriate protective gear to minimize inhalation or skin contact.
8. Regular Check-Ups: Visit your healthcare provider for regular screenings, especially if you have risk factors for head and neck cancer.
9. Be Aware of Symptoms: Early detection is key to successful treatment. Be aware of symptoms such as persistent sores, lumps, or changes in your voice or swallowing, and consult a doctor if they occur.
What is the treatment process for head and neck cancers?
The treatment process for head and neck cancers depends on various factors, including the type, location, stage of the cancer, and the patient’s overall health. Here’s a general outline of the treatment process:
1. Diagnosis and Staging
● Physical Examination: A thorough examination of the head, neck, and throat to detect abnormal lumps, sores, or other signs.
● Imaging Tests: CT scans, MRI, PET scans, and X-rays are used to determine the size and spread of the cancer.
● Biopsy: A tissue sample is taken from the suspicious area to confirm the presence of cancer and determine its type.
● Endoscopy: A flexible tube with a camera is inserted into the nose, throat, or mouth to get a closer look at the affected areas.
2. Treatment Planning
● A multidisciplinary team, including oncologists, surgeons, radiologists, and other specialists, develops a personalized treatment plan based on the patient’s condition.
3. Primary Treatment Options
● Surgery:
○ The goal is to remove the tumor and some surrounding healthy tissue to ensure all cancerous cells are removed. Depending on the location and size, surgeries might involve removing parts of the mouth, throat, or voice box (larynx).
○ In some cases, reconstructive surgery is needed to restore function and appearance.
● Radiation Therapy:
○ High-energy beams, such as X-rays or protons, are used to kill cancer cells. Radiation may be used as the primary treatment, post-surgery to eliminate residual cancer cells, or to shrink tumors before surgery.
○ It can also be used to treat areas that cannot be surgically removed.
● Chemotherapy:
○ Chemotherapy involves using drugs to kill cancer cells. It is often used in combination with radiation therapy (chemoradiation) to increase the effectiveness of the treatment.
○ It may be given before surgery (neoadjuvant therapy) to shrink the tumor, or after surgery (adjuvant therapy) to reduce the risk of recurrence.
● Targeted Therapy:
○ Targeted drugs focus on specific molecules involved in cancer growth, such as the EGFR (epidermal growth factor receptor) protein in some head and neck cancers.
○ This treatment is often used in conjunction with chemotherapy or radiation.
● Immunotherapy:
○ Immunotherapy boosts the body's immune system to fight cancer. It is typically used for advanced head and neck cancers that haven’t responded well to other treatments.
4. Rehabilitation
● Speech and Swallowing Therapy: Post-surgery or radiation therapy, patients may need therapy to regain normal speech, swallowing, and breathing functions.
● Nutritional Support: Dietitians help manage diet and nutritional intake during and after treatment to maintain strength and recovery.
● Physical Therapy: Assists in regaining strength and mobility, particularly if extensive surgery or radiation therapy has affected movement or function.
5. Follow-Up Care
● Regular Monitoring: Post-treatment, regular check-ups are necessary to monitor for any signs of recurrence or complications.
● Supportive Care: Psychological support, pain management, and social services are provided to help patients cope with the emotional and physical impact of cancer treatment.
6. Clinical Trials
● Patients may have the option to participate in clinical trials to access new and potentially more effective treatments.
Each patient's treatment process is unique, and the approach will be tailored to best address the specific needs of the individual.What are the side effects of head and neck cancer?
side effects of head and neck cancer treatment can vary widely depending on the type of treatment, the location of the cancer, and the individual’s overall health. Here are some common side effects associated with the primary treatment options:
