    Dear Readers,

    General Knowledge is important for most competitive exams, namely the UPSC Civil Services Examination, SSC CGL, Bank PO & PSU entrance tests, etc. Therefore, an understanding of the concepts/terms that are significant in our daily lives is critical for aspirants. To make your preparation easier and to help you score better, we at PaGaLGuY bring you brief articles on trending phenomena and concepts.

    One of the deadliest diseases in India and worldwide, Cancer, continues to mercilessly claim millions of lives every year. Approximately 7 lakh Indians die annually with some form of cancer while more than 10 lakh are newly diagnosed for cancers. This article will discuss the basics of Cancer.

    What is a Cancer?

    1. It is a disease caused by rapid and uncontrollable division of abnormal cells in the body.
    2. Normal cells grow and divide after reaching maturity by a process called mitosis and die after certain period in an orderly way termed as apoptosis (programmed cell death). However, cancerous cells do not die but divide rapidly.
    3. This abnormal division gives rise to a lump of cells that contain millions of cells called neoplasm or tumor.
    4. Tumors are of two types: malignant and benign
    5. Benign tumors are non-cancerous forms of cell growths. They divide uncontrollably but do not spread to the other parts and remain localised to their point of origin. For E.g. uterine fibroids, skin moles.
    6. Malignant tumors are cancerous forms of cell growths. Not only do they divide uncontrollably but also spread to the other organs and tissues. This phenomenon is known as metastasis.
