What Is Cancer?

Cancer is a group of diseases characterised by the uncontrolled growth and spread of abnormal cells. Cancer cells develop because of multiple changes in their genes. These changes can have many possible causes. If the spread of cells is not controlled, it can result in death. There are many known causes of cancer; they include tobacco use, smoking, alcohol, excess body weight, inherited genetic mutations, hormones, and immune conditions. These risk factors may act simultaneously or in sequence to initiate and/or promote cancer growth. There are many types of cancer. Cancer can develop anywhere in the body and is named after the part of the body where it started. For instance, breast cancer that starts in the breast is still called breast cancer, even if it spreads (metastasises) to other parts of the body.

Cancer Prevention

Cancer prevention is achieved through primary, secondary, and tertiary methods. Primary cancer prevention is achieved through two mechanisms: the promotion of health and wellness and the reduction of risks known to contribute to cancer development. Primary prevention aims to reverse or inhibit the carcinogenic process through modifications in a patient’s diet or environment. Secondary cancer prevention includes screening and early detection. Screening for cancer refers to checking for the presence of disease in populations at risk, and early detection is defined as testing for cancer when no symptoms are present.

Secondary prevention seeks to detect cancer at the earliest possible stage when the disease is most likely to be treated successfully. Tertiary cancer prevention is applied to those individuals who have already been diagnosed with malignancy but are now candidates for screening and early detection of secondary malignancies.

How to Fight Cancer?

The promotion of a healthy diet and physical activity is one of the best ways to fight against cancer. Avoid the use of alcohol, tobacco, cigarettes and such items which are hazardous to health. Cancer mortality can be reduced if cases are detected and treated early. So, early diagnosis, screening and treatment reduce the severity of cancer; and it can be cured.

Apart from spreading awareness among people and educating them to know the early signs of this disease. Also, the education will upgrade the information about exercise, dietary habits, sun exposure, smoking cessation, and recommended screening practices. We all can together fight against this disease and make our country cancer-free.


Cancer is a dangerous disease, but it can be cured. Required instruments should be provided to the hospitals so that the screening and initial detection of cancer can be done at the early stage. In national health insurance, the treatment of cancer should be included with an emphasis on providing financial support to the patient and his family. The expensive immune and targeted therapies should not only be for those upper-income people. These facilities should be made accessible to all people at affordable costs. Thus, it will increase access to health services and strengthen the health systems for low and middle-income people.
