Cancer prevention and treatment - Cancer Science

What is Cancer?

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If not controlled, it can result in death. Cancer can develop in almost any tissue or organ in the body and is often named for the part of the body in which it originates.

How Can Cancer be Prevented?

Prevention is a critical aspect of reducing the global burden of cancer. Many cancers can be prevented by addressing risk factors such as tobacco use, unhealthy diet, physical inactivity, and environmental exposure to certain chemicals and radiation.
Quit Smoking: Tobacco use is the largest preventable cause of cancer worldwide. Quitting smoking can significantly reduce the risk of lung cancer and other types of cancer.
Healthy Diet: Consuming a diet rich in fruits, vegetables, whole grains, and lean proteins can help lower the risk of cancer. Limiting processed meats and avoiding excessive alcohol intake is also important.
Physical Activity: Regular physical activity can help maintain a healthy weight, which is associated with a lower risk of several types of cancer, including breast and colon cancer.
Vaccination: Vaccines such as the HPV vaccine can prevent infections that lead to certain cancers, like cervical cancer.
Screening and Early Detection: Regular screenings for cancers such as breast, cervical, and colorectal cancer can detect the disease at an early stage when it is more likely to be treatable successfully.

What are the Common Treatments for Cancer?

Cancer treatment varies based on the type and stage of the disease, as well as the patient’s overall health and preferences. Here are some of the most common treatments:
Surgery: Often the first line of treatment, surgery involves the removal of the tumor and surrounding tissue. It is most effective for cancers that are localized and have not spread.
