Renal Cell Carcinoma: Also known as kidney cancer. It is the most common type of cancer seen in adults. This condition occurs when cancer/ malignant cells grow uncontrollably in the kidney and form a tumor. Advanced kidney cancer (metastatic renal cell carcinoma) occurs when the malignant cells spread to other parts of the body. Symptoms include red, orange, or pink-coloured urine due to the presence of blood in the urine.

Hepatocellular carcinoma: Also known as liver cancer. It occurs when the cancer/ malignant cells grow out of control. This infects the liver, destroys the liver cells and affects the ability of the liver to work properly. Symptoms may include abdominal pain, loss of appetite, weight loss, and pale bowel motions.

Differentiated Thyroid cancer: This condition occurs when the cancer cells grow abnormally in the thyroid gland. The thyroid gland is a butterfly-shaped organ present under the neck. This gland is useful in producing hormones responsible for the functioning of the body. Differentiated thyroid cancer is the most common type of thyroid carcinoma, which includes papillary thyroid cancer and follicular thyroid cancer.

Endometrial cancer: It is a cancer which affects the endometrium (lining of the womb or uterus). Symptoms may include bleeding between periods, pelvic pain, and pain during sexual intercourse. This cancer mostly occurs due to certain factors such as increasing age, obesity, never being pregnant, family history of cancer, and diabetes. It is usually seen in women above the age of 55 years. This condition is not life-threatening when it is diagnosed and treated in the early stages.
