Cancer is a disease in which abnormal cells divide without control and are capable of invading other tissues. These cancer cells can spread to other parts of the body through the blood and lymph systems. Not only makes the body attacked by various diseases, but cancer cells can also cause death.
Many people think that cancer is a person's destiny, there are also those who think that it is due to an unhealthy lifestyle, and there are also those who think that cancer is caused by heredity.
Based on research conducted by Johns Hopkins University, two out of three cases of cancer in adults are triggered by mutations in a gene that attacks randomly, which then causes tumors. Studies show that in general changes in the number of stem cell divisions in a tissue type are highly correlated with changes in cancer incidence in the same tissue. That is, the higher the number of tissue cell divisions in the body, the higher the risk of cancer.
Even so, it does not mean that an unhealthy lifestyle cannot trigger cancer. Several types of cancer such as skin cancer, neck, head, colon, rectum (colon and anus), and lung cancer are caused by an unhealthy lifestyle and there are also hereditary factors. In conclusion, cancer is the result of a combination of factors such as genetics, environment, and random gene mutations.
Cancer can attack anyone, any part of the body, and also in all age groups without exception. If you feel the appearance of a lump or tumor in one part of the body, it is better to immediately go to the hospital to prevent cancer cells from expanding or damaging the surrounding tissue.
