Cancer is a condition where cells in a particular part of the body develop and reproduce uncontrollably. Cells can
experience uncontrolled growth if there are mutations to DNA, and it alters genes involved in cell division.
Cancer occurs when a cell’s gene mutations make the cell unable to correct DNA damage. Normal cells in the body follow grow, divide and die.
Cancerous cells can destroy other healthy tissue and organs in the body, cancer can grow in any part of the body.
There are over 220 different types of cancer.
It alters normal cells division to form lumps or masses of tissue known as tumors. Tumors interfere with the digestive, nervous, and circulatory systems, and release hormones that alter proper body functions. Metastasis is multiplication and spread of cancers to other parts of the body to invade and destroy other healthy tissues.
Cancer is considered to be one of the leading causes of morbidity and mortality worldwide. Carcinogens are tobacco, asbestos, arsenic, radiation such as gamma and x-rays, the sun, and compounds in car exhaust fumes are all examples of carcinogens.
When our bodies are exposed to carcinogens, free radicals are formed that try to steal electrons from other molecules in the body. Theses free radicals damage cells and affect their ability to function normally.
Cancer can be the result of a genetic predisposition that is inherited from family members. It is possible to be born with certain genetic mutations or a fault in a gene that makes one more likely to develop cancer later in life.
African Americans are more likely to die of cancer than people of any other race. Risk of cancer can be reduced by avoiding tobacco, limiting alcohol intake, limiting UV ray exposure from the sun and tanning, eating healthy diet, and regular medical check.
There is an increase in the number of possible cancer-causing mutations in our DNA as we get older. Some viruses like human papillomavirus, hepatitis B and C and E, Human immunodeficiency virus and any disease that suppresses the immune system increases the risk of developing cancer.
