Cancer is a term for a group of diseases where your body’s cells grow abnormally and uncontrollably in any organ or tissue. They can spread to any part of your body and cause severe consequences. In 2020, cancer was the leading cause of mortality worldwide. Stomach, lung, colon, prostate, skin, and breast cancers were the most common types of cancer that affected the world population [1]. World Cancer Day is celebrated as an international awareness day led by the Union for International Cancer Control (UICC) to raise worldwide attention and inspire action for a cancer-free future.

Around 30% - 50% of cancer cases can be prevented by making lifestyle changes or avoiding risk factors [2]. Some cancer treatments include chemotherapy, immunotherapies, surgery, and radiotherapies [3]. World Cancer Day raises awareness to prevent and treat the disease better. Read on to know more about cancer and the importance of International Cancer Day.

Types of Cancer 

There are over 100 types of cancer. These are known for the organs and tissues they form. Here are some categories of cancers:


These cancers form in bone and soft tissues. They include blood vessels, lymph vessels, fat, muscle, and fibrous tissue. Osteosarcoma is a common type of bone cancer. Kaposi sarcoma and liposarcoma are some types of soft tissue sarcoma.


These common types of cancer are formed by epithelial cells. Epithelial cells cover the inner and outer surfaces of the body. Adenocarcinoma, Basal cell carcinoma, Squamous cell carcinoma, and transitional cell carcinoma are some types of cancer caused by epithelial cells.


Leukemia originates in the bone marrow. These cancers occur when abnormal white blood cells build up in the bone marrow and the blood. The excess of abnormal white cells as compared to normal blood cells makes it difficult for your body to receive enough oxygen for normal function. Acute, chronic, lymphoblastic, myeloid are four common types of leukemia.


Hodgkin lymphoma and non-Hodgkin lymphoma are two main types of lymphoma. Lymphoma forms from B cells or T cells – lymphocytes. When abnormal lymphocytes form in lymph nodes or lymph vessels, it can lead to lymphoma.


Melanoma usually forms on the skin. It can also occur in pigmented tissues including the eye. The disease occurs in cells that become melanocytes, the cells that produce melanin. 

Multiple myeloma

Multiple myeloma is also known as Kahler disease or plasma cell myeloma. It occurs when abnormal plasma cells grow in the bone marrow forming tumors throughout the body. Plasma cells are types of cells in your immune system.

Brain and spinal cord tumors

There are many brain and spinal cord tumors. As with other types of cancer, the names are determined depending on where the tumor initially formed and the type of cell in which it developed. Tumors of the brain can either be benign or malignant.
