Nt1310 Unit 1 Assignment
Cancer Assignment: Part A
1. 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 interphase 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 tumour. The cells of the tumour may stay together and have no other effect on the tissues around it, this is known as a benign tumour. There is also a tumour known as a malignant tumour, which causes interference with functioning of neighbouring cells and tissues. Malignant tumours could even destroy surrounding tissues, but malignant …show more content…
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 cytokinesis. Some mutations are caused by carcinogens: environmental factors that cause cancer, some include, tobacco smoke, radiation, such as x-rays and UV 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 PSA, 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
