It is rare type of cancer. Tobacco and alcohol use can increase the risk of larynx cancer. Sore throat and ear pain are the most common signs and symptoms of larynx cancer. Most laryngeal cancers start in the flat, scale-like squamous cells that line the inner walls of the larynx. It can also spread to the tongue, throat, neck, lungs and other parts of body.

There are 5 main T stages for cancer of the larynx – Tis to T4.

Tis (tumour in situ) : It very early stage of larynx cancer and has not spread into surrounding tissue. It is contained in the top layer of the skin like covering of the larynx (mucosa).

T1:  Tumour is present only in one part of the larynx and the vocal cords are able to move normally.
T2:  Tumour may have started on the vocal cords (glottis), above the vocal cords (supraglottis) or below the vocal cords (subglottis) and has grown into another part of the larynx.
T3:  Tumour become more bulky and may cause one of the vocal cords to not move. Or the tumour has grown into nearby areas such as the tissue in front of the epiglottis (pre-epiglottis tissues) or the inner part of the thyroid cartilage.
T4 :  Tumour has grown into body tissues outside the larynx and it may have spread to the thyroid gland, windpipe (trachea) or food pipe (oesophagus).

Node (N)
Node (N) describes whether the cancer has spread to the lymph nodes.
There are 4 main N stages for cancer of the larynx – N0 to N3. N2 is split into N2a, N2b and N2c.
N0 : In this stage lymph nodes don’t contain cancer cells.
N1 : Lymph node contains cancer cells
N2a: Lymph node contains cancer cells on the same side of the neck as the cancer. And the node is between 3cm and 6cm across.
N2b : More than one lymph node contain cancer cells on the same side of the neck as the cancer. But none of the nodes are more than 6cm across.
N2c : Cancer cells in lymph nodes on the other side of the neck from the cancer, or in nodes on both sides of the neck. But none of the nodes are more than 6cm across.
N3 : At least one lymph node containing cancer cells is larger than 6cm across.

Metastasis (M)
Metastasis (M) is used to describe whether cancer has spread to other parts of body.
There are 2 stages of metastasis – M0 and M1.
M0 means there is no cancer spread.
M1 means the cancer has spread to other parts of the body, such as the lungs.
