A doctor who identifies diseases by studying cells and tissues under a microscope.
Patient advocacy organisation
An organisation that generally provides disease and treatment information and emotional support to patients, family members and caregivers, and helps a patient work with others who have an effect on the patient's health, including doctors, insurance companies, employers, case managers, and lawyers. A patient advocacy organisation may help resolve issues about health care, medical bills, and job discrimination related to a patient's medical condition. Cancer advocacy groups also try to raise public awareness about important cancer issues, such as the need for cancer support services, education, and research. Such groups work to bring about change that will help cancer patients and their families.

PET scan
A procedure in which a small amount of radioactive glucose (sugar) is injected into a vein and a scanner is used to make detailed, computerised pictures of areas inside the body where the glucose is used. Because cancer cells often use more glucose than normal cells, the pictures can be used to find cancer cells in the body. Also called positron emission tomography scan.

In cancer, survivorship covers the physical, psychosocial, and economic issues of cancer, from diagnosis until the end of life. It focuses on the health and life of a person with cancer beyond the diagnosis and treatment phases. Survivorship includes issues related to the ability to get health care and follow-up treatment, late effects of treatment, second cancers, and quality of life. Family members, friends, and caregivers are also part of the survivorship experience.

Thorax
The part of the human body between the neck and the diaphragm, partially encased by the ribs and containing the heart and lungs. Often referred to as the chest.
Tyrosine kinase
An enzyme that adds a phosphate residue to a tyrosine, which results in a change in function of the tyrosine protein. Tyrosine kinases play a major role in the cell division process, signalling the section of the cell cycle known as mitosis to begin.
TKI (tyrosine kinase inhibitor)
A drug that interferes with cell communication and growth and may prevent tumour growth. Some tyrosine kinase inhibitors are used to treat cancer.
TNM staging
A system to describe the amount and spread of cancer in a patient’s body, using TNM. T describes the size of the tumour and any spread of cancer into nearby tissue; N describes spread of cancer to nearby lymph nodes; and M describes metastasis (spread of cancer to other parts of the body). This system was created and is updated by the American Joint Committee on Cancer (AJCC) and the International Union Against Cancer (UICC). The TNM staging system is used to describe most types of cancer. Also called AJCC staging system.
