Different types of Cancers Cancer is a very broad topic. It involves numerous types all of which have extremely diverse causes, signs and symptoms, pathological features & require specific investigations and treatment. We will discuss about the 10 most common types of cancers based on their prevalence worldwide. Along with it, the important subtypes that form the vast majority of cases. Cancer involves almost all organs and tissues, hence cancer typing is based on the specific organ it affects. ex. Lung Cancer, Prostate Cancer, Skin Cancer, etc. Further subtyping is done according to the cell line which is defective. ex Small cell cancer, B cell Lymphoma, Granulosa cell tumor, Germ cell tumor, etc.

After knowing the basics about cancer , lets move on to the main causes of cancer . What are the main reasons behind such uncontrolled proliferation of cells? Normally division of cells is under control of  various genes which are known as tumor suppressor genes. There are also other counterparts which promote cell proliferation known as Proto-oncogenes . But both those processes are well regulated and there are multiple checks which prevent or repair the damage. Hence for cancer to occur there has to be some defect in either Tumor Suppressor Genes or Proto-Oncogenes .
