Head and Neck Cancer Market |
The way a specific head and neck cancer behaves is
determined by the spot where it develops (the primary site). Cancers that start
in the vocal cords, for example, behave substantially differently than cancers
that start in the back of the tongue, which is only an inch or less away from
the vocal cords.
Squamous cell carcinoma is the most frequent type of cancer
in the head and neck, and it develops from the cells that line the inside of
the nose, mouth, and throat. A history of smoking or exposure to the human
papillomavirus is frequently linked to squamous cell carcinoma (HPV). Salivary
gland tumours, lymphomas, and sarcomas are some of the less prevalent kinds of
head and neck malignancies.

Cancer can spread in one of four ways. The first is a
straight extension from the main site to the surrounding areas. The second is
transmitted to lymph nodes via lymphatic pathways. The third is spread along
nerves to other parts of the head and neck (perineural spread). The fourth is
transported to distant parts of the body via blood vessels. The spread of head
and neck cancer to the lymph nodes in the neck is rather common.
The lymph nodes that are most usually affected are
determined by the original tumor's location. The majority of lymph nodes are
found beneath the sternocleidomastoid muscle on each side of the neck, along
important blood veins. If the cancer has advanced to the lymph nodes in the
neck, the number of nodes involved, and their position in the neck, the risk of
spreading to other areas of the body through the bloodstream is closely
associated. If cancer is found in lymph nodes in the lower area of the neck
rather than those in the upper, the risk is increased.
A dentist, oral surgeon, or physician may diagnose cancer of
the head and neck if a patient detects signs such as a lump in the neck or an unhealed
sore in the mouth. The diagnosis might be made during a normal examination even
if there are no symptoms.
