Cancer is any of a range of diseases that emerge when abnormal cells divide uncontrollably and spread to other tissues and organs. Moreover, it is capable of infiltrating and destroying normal bodily tissue. Cancer has the potential to spread throughout your body.

Also, it is one of the world’s major causes of death, as it is the second-leading cause of death in the world. Moreover, cancer will account for nearly one in every six deaths in 2020, according to the World Health Organisation (WHO). So every day experts labor tirelessly to invent new cancer treatments.

Types of cancer

There are about 100 different forms of cancer, which are usually called after the organs or tissues where they develop. Moreover, the most prevalent cancers in men include lung, prostate, stomach, colon, and rectum tumors, and breast, colon, rectum, lung, and cervical cancers are the most prevalent in females.

So some of the common types of cancers are:

  • Bladder cancer
  • Brain cancer
  • Bone cancer
  • Liver cancer
  • Lung cancer
  • Thyroid cancer
  • Breast cancer
  • Colorectal cancer
  • Endometrial cancer
  • Kidney cancer
  • Leukaemia 
  • Melanoma 
  • Pancreatic cancer
  • Non – Hodgkin Lymphoma
  • Prostate cancer

There are numerous types of cancer in human body parts. But these are arranged into a few specific categories.

Carcinoma: Cancer that begins in the skin tissues that cover internal organs Skin, lung, epithelial, squamous, and basal cell carcinomas, colon, pancreatic, ovarian cancers, melanomas, papillomas, and adenomas.

Sarcoma: Cancers in bone, cartilage, fat, muscle, blood vessels, or other connective tissue bone, soft tissue cancers, osteosarcoma, liposarcoma, synovial sarcoma, angiosarcoma, rhabdomyosarcoma, and fibrosarcoma.

Leukemia: Cancer that begins in blood-forming tissues such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood. lymphoblastic leukemia, myelogenous leukemias, hairy-cell leukemia, and T-cell leukemia

Lymphoma and myeloma: Cancers in the immune system, T-cell lymphomas, B-cell lymphomas, and Hodgkin lymphomas are examples of leukemia.

Central nervous system cancers: Cancers in the tissues of the brain and spinal cord, gliomas, meningiomas, pituitary adenomas, primary CNS lymphomas are a few central nervous system cancers.

Causes of cancer

Anything that causes abnormal development of a normal bodily cell has the potential to produce cancer so many factors can induce cell abnormalities, which have been related to the development of cancer.

Some cancers have unknown causes while others have environmental or lifestyle triggers or may arise from more than one recognized to cause. 

But some may be influenced by a person’s genetic build in terms of development. Also, a combination of these variables causes cancer in many people.

The mutation that happens within the cells causes cancer. Inside a cell, DNA is packaged into many separate genes, each of which includes a set of instructions informing the cell what functions to execute as well as how to grow and divide. Hence errors in the instructions can cause the cell to stop functioning normally and even cause it to become cancer hence causes of cancers include:

  • Gene mutations
  • Tobacco intake
  • Infections like hepatitis B and C and human papillomavirus
  • Immunosuppressive medicines
  • Exposure to ultraviolet radiations and x rays
  • Environmental pollutants

Metastatic cancers are not included in the above types because metastatic cancer cells usually arise from one of the above cell types. But the major difference is that these cells are now present in a tissue from which the cancer cells did not originate.

Prevention from cancer

  • Avoiding known causes of cancer like 
  • Changes in lifestyle
  • Regular body checkups
  • A diet low in fat and high in fibre and addition of fruits and vegetables lowers the risk of many types of cancers.
  • Vaccination against hepatitis B and human papillomavirus.
  • Taking tests at regular intervals of those who are at higher risk,

So early identification of cancer through regular health exams is a useful technique for discovering cancer at its forming stages, where treatment is still effectively possible.

Moreover, if you think you are having symptoms of cancer book an appointment with your doctor at the earliest.
