effect of cancer on human body

Cancer is a group of diseases in which cells grows and divide out of control, it is caused by a change in DNA that controls the cell cycle. This DNA change causes for cells not to stay in enterprise for the normal amount of time, and some of the checkpoints fail and cause the cells to divide uncontrollably. The uncontrollable division rate can create a massive group of cells called a tumor. The cells of the tumor may stay together and have no other effect on the tissues around it, this is known as a benign tumor.

There is also a tumor known as a aligning tumor, which causes interference with functioning of neighboring cells and tissues. Malignant tumors could even destroy surrounding tissues, but malignant tumors are considered cancerous. 2. When a cell divides, it’s DNA is copied error-free, but sometimes random changes occur called mutations. The changes can result in the death of the cell or allow the cell to live and continue to grow and divide. When the DNA starts to act abnormally, the cells could become cancerous and proliferate wildly through repeated, uncontrolled mitosis and woodiness.

Some mutations are caused by carcinogens: environmental factors that cause cancer, some include, tobacco smoke, radiation, such as x-rays and IV rays from tanning beds and sunlight. 3. Cancer screening is checking for cancer even if there isn’t any symptoms. A pap test is a where a doctor takes cervical cells and tests them for cancer. Men can detect testicular cancer through self examination. There’s also a blood test called the AS that a doctor can prescribe for prostate cancer. 4. Many things can affect a persons risk of getting cancer.

These risks include tour personal and family medical history, carcinogens in your environment and your lifestyle choices. There are many lifestyle choices, that can help reduce your risk of developing cancer. A healthy diet that contains lots of fruits and vegetables. Research has shown that certain “super foods” contain substances that help your body protect itself from cancers. 5. In some cases of cancer, a growing tumor can create swelling or cause discomfort. The earlier that cancer is diagnosed it has better chances of being treated and lesser chance of it spreading. Says of diagnosing cancer are imaging technologies and examining cells. Some imaging technologies include endoscope, X-ray, ultrasound, CT scanning and MR.. An endoscope is for colon cancer, X-ray is to view parts of the body, CT scans can take multiple X-rays of the body in other angles. If any of those tests show abnormalities the doctors examine the patients cells, and also the only way of diagnosing cancer. 6. There are many ways to treat cancer, but some ways are easier to cure if they aren’t really severe. You can use surgery to remove cancerous tissue, and this is preferred way to treat cancer.

There is also chemotherapy which treats cancer using drugs. These drugs cause cancer cells to slow down and divide slower and prevent the cells from moving to different parts of the body. There is also radiation therapy. Cancer cells get damaged easily by ionizing radiation, the DNA of the daughter cells are damaged by radiation so they can no longer divide. Another way of treating cancer is photocopies, it is a newer method of treating caner. It uses beams of light to find and treat the cancer, it can also detect cancer very early on.
