Knowing Some Types Of Cancer

Cancer is one of the most life-threatening diseases that impair the quality of life to a great extent. There are more than hundred types of cancer and people across the world can suffer from any type. Some of the types of cancer and their effects on an individual’s health are:

Brain tumor

The brain is an elegant and sophisticated mass of tissue and nerve cells that regulate the vital body functions and also controls the senses and personality. A tumor is defined as an abnormal tissue that grows by an uncontrolled cell. A brain tumor can be primary or secondary.

  • Primary Brain Tumor -  A primary brain tumor is that condition in which an abnormal growth starts in the brain and does not spread to other parts of the body. A primary brain tumor can further be categorized into benign and malignant, a benign brain tumor is a slowly growing tumor which has distinct boundaries and it rarely spreads.  A malignant brain tumor is a quickly growing tumor that has irregular boundaries and it can spread to the nearby areas of the brain.

  • Secondary Brain Tumor - A secondary brain tumor is also known as metastatic brain tumor and it begins as cancer in other parts of the body and then spreads to the brain. Lung cancer and the breast cancer are the most common cancer that spreads to the brain.

A brain tumor can occur at any age and whether a brain tumor is a primary type or secondary type, it is life threatening. Some of the symptoms that occur in brain tumor are persistent headaches, problems in balancing, weakness, numbness, and changes in vision, speech or hearing.

Bowel Cancer

Bowel cancer is cancer that occurs in any part of the large bowel i.e colon or rectum and sometimes it is also known as colorectal cancer. Colorectal cancer grows from the inner lining of the colon and it usually develops from the growth of the bowel walls and these growths are known as polyps. A colon and rectum together make up large intestine and the colon is a muscular tube that collects and stores waste and then passes it to the rectum. Not all polyps become cancer and it depends on the type of polyp but some can change into cancer over time. Adenomatous and hyperplastic are two types of the polyps. Adenomatous is also known as a precancerous condition and this type of polyp can change into cancer. Hyperplastic polyps are more common and they generally do not change into cancer. Various risk factors have been revealed for colorectal cancer such as age, gender, race, smoking, family history, diet, and obesity. A colonoscopy is considered to be an effective screening test to diagnose colon cancer and is any polyp is found then during colonoscopy, the doctor removes the polyp using an instrument.

Leukemia

Leukemia is a medical term which is used to target the cancer of the blood cells. Blood is consist of different types of cells in the body such as white blood cell, red blood cell and platelets and when the control of the body over the white blood cells is disturbed, it leads to the development of leukemia. There are different types of leukemia and the main types include,  acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), acute lymphocytic leukemia (ALL) and chronic lymphocytic leukemia (CLL). In acute myelogenous leukemia and acute lymphocytic leukemia, the acute leukemia cell form trillion more leukemia cells and these cells are known as non-functional cells as they are abnormal cell and do not function normally. In chronic myelogenous leukemia, the leukemia cells forms the blood cells that function normally and the number of red cells are less than the normal and causes anemia. White blood cells function normally but their count decreases and require treatment. Chronic lymphocytic leukemia makes many lymphocytes that do not function and these cells replace the normal cells and lead to the development of another health problem.

Kidney Cancer

Kidneys are the two bean-shaped organ that plays the main role to clean and filter the blood. Blood goes into each kidney and is filtered through the nephrons and then goes back to the entire body. Kidney cancer is cancer that usually starts in the cells of the kidneys and renal cell carcinoma is the most common type of kidney cancer in adults. It usually begins in the lining of renal tubules which are the tubes in the kidneys. There are many types of renal cell carcinoma and of which some can spread very quickly and others might take a time or are less likely to spread. Papillary, chromophobe, and clear cell are some common types of renal cell carcinoma. There are various risk factors that are associated with renal cell carcinoma and tobacco use is one of the most important factors. According to the researchers, people who consume tobacco are at a higher risk of developing renal cell carcinoma as compared to those who do not use tobacco. Other risk factors include hypertension, obesity, and long-term use of analgesics.
