About Medical Oncology
Medical Oncology involves diagnosis and treatment of cancer using chemotherapy, and other treatments like immunotherapy, targeted therapy, and hormone therapy.
The chemotherapy treatment process uses drugs to destruct cancer cells. The treatment works around a pattern, stopping or slowing the growth of cancers cells. The treatment can harm the dividing healthy cells in the process.
Chemotherapy is divided into two categories- neoadjuvant and adjuvant chemotherapies. Neoadjuvant chemo is delivered before surgery or radiotherapy, while adjuvant chemo is delivered after the surgery or radiotherapy.
Immunotherapy process involves activating the immune cells to fight against the cancer cells. This personalised treatment aims to strengthen body’s defence mechanism to fight and destroy cancer cells. Patient’s own body cells are used, or treatment is designed in a laboratory to improve the functioning of immune system
Targeted therapy process also uses drugs but it differs from the traditional chemotherapy. This treatment uses drugs that specifically target genes or proteins that are found in cancer cells or in cells that can be related to cancer growth, to stop cancer from growing and spreading to other body organs.
Specific cancers are hormone sensitive, using hormones to grow or develop. Hormone therapy uses medicines to block or restrict the number of hormones in the body to stop or slow down cancer growth and prevent cancer cells from growing and dividing.
Hormone sensitive cancer include : Breast cancer, Prostate cancer, Ovarian cancer, Uterine cancer
