Exercising as a cancer survivor

Physical activity helps to increase white blood cell count. White blood cells are critical to the immune system's ability to contain and/or eliminate cancer cells from the body. Regular physical activity can help maintain a healthy body weight and minimise the negative effects of cancer. Excess body weight has been linked to the development several types of cancer.

Less fatigue

Physical activity has been very effective in the management of prostate cancer. Men who exercise and remain generally healthy are more tolerant of a greater range of cancer-treatment options. Men who are not healthy enough to undergo surgery will limit their treatment options. Men who are physically active experience less fatigue and other side effects from common prostate-cancer treatment such as radiation therapy.

Being physically active improves the survival and quality of life of those diagnosed with cancer. Being physically active lowers the risk of developing lung cancer. This benefit is enjoyed by people who are smokers or who are at high risk for lung cancer. Cancer-related fatigue, depression and mood swings have been described as some of the most distressing cancer symptoms, and patients have confirmed exercise as one of the best options to manage these side effects.

The functional capacity of the lungs is increased with exercise. It also helps to change body mass index by increasing muscle mass. A reduction in the experiences of nausea, improved work capacity, lower heart rate , improved blood pressure, increased maximum workload and an increase in the time it takes to become exhausted, as a result of regular physical activity, have all been confirmed by cancer patients.

Helps depression

Anxiety and depression are common among cancer patients and physical activity has been very effective in addressing these problems. This type of relief actually benefits the immune system and has been confirmed by cancer patients who engage in moderate walking on a daily basis. The frequency and duration of exercise sessions are very significant to the cancer patient. A routine of three sessions each week for a total of 60 minutes each day is effective. However, an alternative option of six days each week for a total of 30 minutes each day is also good. However, varying the exercise programme should not compromise your tolerance level.

The intensity of the exercise should be moderate. Aerobic activities such as cycling, swimming jogging, walking, calisthenics and light weight training are recommended. Choose activities that are appropriate to your present physical ability. If you have been inactive, consult your doctor before starting an exercise programme.
