How to Prevent Cancer

Some tumors stick on one spot, however, these account for only 10% of all deaths (Medical News Today, 2013). However, I believe that cancer is a preventable disease that requires lifestyle changes.Cancer has no definite way of treatment. Patients are mostly given a combination of therapies and medical care that do not cure the disease, but rather relieve the patients of pain and prevent the cancerous cells from spreading. They include immunotherapy, gene therapy, chemotherapy, radiation, hormone therapy and surgery to remove the tumors at primary stages of infection. It is due to the inability to cure this disease that doctors advocate for prevention. Exercises and dietary changes are the only ways of cancer prevention. There are other ways of prevention, however, lifestyle changes in diets and exercises are at the pinnacle of these methods.Physical inactivity is linked to many health problems including obesity. Regular exercises reduce obesity which is associated with different strains of cancer such as breast, kidney, endometrium, colorectum, and esophagus (WHO, 2014). It is also worth noting that obese cancer survivors find it hard to fight cancer after surgery. The American Cancer Society Cancer Prevention Study showed that obese men suffering from prostate cancer and obese women diagnosed with breast cancer had an increase risked compared to their normal counterparts and were, therefore, more likely to succumb to these illnesses even after successful surgery.As of 2013, more than 1/3 of American adults are overweight and another 1/3 considered obese. 17% of young adults and children are also obese. This means that the number of obese people has increased by 300% since the ‘80s (Foxhall, 2013). According to Karen Basin-Engquist (Professor, Department of Behavioral Science at The University of Texas MD Anderson Carter Center), obesity leads to over-production of estrogen among women, which is a contributing factor in breast cancer. Breast tumors are known to thrive in estrogen conditions and hence higher estrogen levels facilitate rapid replication of ‘hormone positive cancerous cells’.
