Cancer is the abnormal growth of cells. Cancer harms the body when altered cells divide uncontrollably to form lumps or masses of tissue called tumors. A primary tumor is the name for where a cancer starts. Cancer can sometimes spread to other parts of the body – this is called a secondary tumor or a metastasis. Cancer and its treatments can affect body systems, such as the blood circulation, lymphatic and immune systems, and the hormone system.


More dangerous, or malignant, tumors form when two things occur:

  1. a cancerous cell manages to move throughout the body using the blood or lymphatic systems, destroying healthy tissue in a process called invasion
  2. that cell manages to divide and grow, making new blood vessels to feed itself in a process called angiogenesis.

Cancer is ultimately the result of cells that uncontrollably grow and do not die. Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form. Unlike regular cells, cancer cells do not experience programmatic death and instead continue to grow and divide. This leads to a mass of abnormal cells that grows out of control.

It is said that there are around 200 types of cancers. The most common type of cancer that are diagnosed with greatest frequency are:

    Anal Cancer occurs in the anus, located at the end of the gastrointestinal tract.  Most anal cancers are squamous cell cancers. Squamous cells are a type of cell that line the surface of the anal canal. Rarer types of anal cancer include basal cell carcinoma, melanoma and adenocarcinoma of the anus, a cancer of the cells that make the mucus that helps the stools (faeces) move smoothly out of the anus.
    1: Bleeding from the rectum

    Bladder Cancer occurs when uncontrolled cells develop in the bladder, the organ that collects urine from the kidneys before eliminating it from the body through urination. There are different types of bladder cancer:
    1: Urothelial carcinoma, formally known as transitional cell carcinoma, is the most common form of bladder cancer (80-90%) and starts in the urothelial cells in the bladder wall’s innermost layer
    2: Squamous cell carcinoma begins in the thin, flat cells that line the bladder
    3: Adenocarcinoma is a rare form which starts in mucus-producing cells in the bladder.Bladder cancer is estimated to result in more than 15,000 deaths in the U.S. in 2014. Muscle-invasive bladder cancer is the deadliest type of the disease.

    Brain Tumor happens when abnormal cells form within or close the brain. Any growth inside the enclosed space of brain can cause many problems.There are more than 40 major types of brain tumours, which are grouped into two main types:
    1: benign – slow-growing and unlikely to spread. Common types are meningiomas, neuromas, pituitary tumours and craniopharyngiomas.
    2: malignant – cancerous and able to spread into other parts of the brain or spinal cord. Common types include astrocytomas, oligodendrogliomas, glioblastomas and mixed gliomas.

After knowing the major types of cancer, you can make sure to get yourself or your family member suffering from cancer free from cancer. It is our duty to get society cancer rid by awaring them about the cancer. To know more about cancer and its types you can contact Radix Healthcare.
