Welcome to Bupa's health hub of information on cancer.

Lung cancer

Lung cancer is the uncontrolled growth of cells in the lungs. This creates a lump (tumour) that can be either malignant (cancerous) or benign (not cancerous).

Bone cancer

Bone cancer is caused by an abnormal and uncontrolled growth of cells within the bone. It can be benign or malignant.

Ovarian cancer

In ovarian cancer, cells in your ovaries start to grow abnormally and out of control.

Prostate cancer

Your prostate is a gland that produces the liquid part of semen. It's about the size of a walnut and lies at the base of your bladder.


Radiotherapy can be used to treat many different types of cancer. Radiotherapy works by destroying the DNA inside cancer cells, preventing them from reproducing and so shrinking cancerous tumours. Normal cells will also be affected but they are better able to repair themselves.

Skin cancer

An abnormal or uncontrolled growth of the cells of the skin can be benign or malignant. If it's malignant, it's called skin cancer. A malignant growth can invade neighbouring tissues or spread to distant organs in the body (metastasis).

Thyroid cancer

The thyroid gland is an endocrine gland. It produces hormones that travel around your body in your bloodstream.


Chemotherapy is used to destroy many different types of cancer at various stages. Chemotherapy medicines can stop cancer cells dividing and reproducing. Your healthy cells can repair the damage caused by chemotherapy, but cancer cells can't and eventually die.

Breast cancer

Breast cancer is a tumour in the breast that contains cancerous cells. A breast tumour is a lump created by an abnormal and uncontrolled growth of cells. It can either be malignant (cancerous) or benign (not cancerous).

Liver cancer

Cancer that starts in your liver is called primary liver cancer. About 1,800 people are diagnosed with liver cancer each year in Hong Kong.

Cervical cancer

There are two main types of cervical cancer. Sometimes, cervical cancer can be a mixture of the two types.

Bowel cancer

Bowel cancer, also known as colorectal cancer, is the name for any cancer of your large bowel and rectum (back passage). Very rarely, cancers can occur in your small bowel.


White blood cells are made in your bone marrow - the soft, spongy centre of your bones. They are involved in your immune system, which defends your body against infection and other harmful substances. There are two main types of white blood cell. These are myeloid cells and lymphocytes.
