Determining the specific stage of head and neck cancer is the initial step toward its treatment, consult with a Surgical Oncologist in Goa to know your condition. Mostly, stage I and II cancers are not dangerous as they do not spread to other body parts from their original location and can be cured. Stage III and IV cancers spread to nearby lymph nodes and form large tumours. Hence, it requires complicated treatment and may have a very low chance of cure. The most common treatment for head and neck cancer involves:
Surgery
Radiation therapy
Chemotherapy
New treatments have been developed for treating head and neck cancer that mainly involve the use of drugs that aim to block the hormones, causing some tumour cells to multiply. This is known as hormone therapy, which makes tumours sensitive to radiation. Another development includes immunotherapy, newer radiation techniques, and advanced surgical techniques for removing the tumour.

Quitting all types of tobacco and related products such as cigarettes, cigars, pipes, snuff, etc. reduces the chances of head and neck cancer.
