Cancer is a disease where body cells grow exponentially and spread to other parts of the body as well.
A human body is made up of billions of cells and cancer can start anywhere in the body. Generally, new cells replace the old cells, and these new cells again grow and multiply into another set of new cells. This is a continuous process happening inside the body.
Sometimes some damaged cells grow and multiply themselves and form tumors. Tumors can contain cancer, but all tumors are not cancerous.
When this cancerous tumor travels inside the body and attacks normal cells, this process is called metastasis.
Signs and symptoms caused by cancer will vary from body to body but some of the generic symptoms include:
- Lump or area of thickening that can be felt under the skin
- Weight changes, including unintended loss or gain
- Skin changes, such as yellowing, darkening, or redness of the skin, sores that won’t heal, or changes to existing moles
- Changes in bowel or bladder habits
- Persistent cough or trouble breathing
- Difficulty swallowing
- Persistent indigestion or discomfort after eating
- Persistent, unexplained muscle or joint pain
- Persistent, unexplained fevers or night sweats
- Unexplained bleeding or bruising
Types of Cancer
There are more than 200 varieties. Generally, the type belongs to the name or tissue from where cancer is originating. For example, brain cancer starts in the brain, lung cancer starts from the lung, etc. National cancer institute has a list of cancer from A-Z. you can visit that NCI for more info about the cancer name. Anyways, we are going to discuss widely affected types of cancer.
Malignant growths that start in the blood-framing tissue of the bone marrow are called leukemias. These diseases don’t shape strong cancers. Unlike solid tumors, a large number of abnormal blood cells are combined in the blood and bone marrow. It made it difficult for the normal blood cells to function. Sudden increases in these abnormal white cells can cause serious health issues and if not treated on time it can be deadly.
There are 4 different categories based on the severity of this disease. Intense types of leukemia develop rapidly, and persistent structures develop all the more leisurely.
Lymphoma is a malignant growth that starts in lymphocytes (Immune system microorganisms or B cells). These are illnesses battling white platelets that are important for the invulnerable framework. In lymphoma, unusual lymphocytes develop in lymph hubs and lymph vessels, as well as in different organs of the body.
There are two main types of lymphoma:
Hodgkin lymphoma – People with this disease have abnormal lymphocytes that are called Reed-Sternberg cells. These cells usually form from B cells.
Non-Hodgkin lymphoma – This is a large group of cancers that start in lymphocytes. These cells can grow rapidly and form T or B cells as well.
Multiple myeloma is a malignant growth that starts in plasma cells, one more kind of safe cell. The unusual plasma cells, called myeloma cells, develop in the bone marrow and structure cancers in bones generally through the body. Various myeloma is additionally called plasma cell myeloma and Kahler sickness.
Melanoma is a malignant growth that starts in cells that become melanocytes, which are particular cells that make melanin (the shade that gives skin its tone). Most melanomas structure on the skin, yet melanomas can likewise frame in other pigmented tissues, like the eye.
Brain and Spinal Cord Tumors
There are various kinds of mind and spinal string cancers. These are named in view of the sort of cell in which they are shaped and where the growth was previously framed in the focal sensory system. For instance, astrocytic cancer starts in star-molded synapses called astrocytes, which assist with keeping nerve cells sound. Cerebrum growths can be harmless (not disease) or threatening (malignant growth).
