Many factors can put a person at risk for cancer. They can be biological, environmental, and also certain lifestyle habits. Some factors are held responsible for the development of cancer more than others. While there are several common cancer treatments available, not all can cure the condition. Some treatment methods only decrease the symptoms and help the affected person lead a better life.

The risk factors associated with cancer can include:

1. Biological risk factors
Biological risk factors comprise age, gender, and various types of inherited diseases. As cancer takes time to develop, most people diagnosed with cancer are above 65 years of age. Though older people are at a higher risk of this disease, it can occur at any age.

People who share a family history of different forms of cancer are likely to develop the disease. Besides, various chronic health conditions can also increase the chances of developing this condition. It is therefore advised to consult a physician to know more about the risks involved. Doctors generally consider these factors when diagnosing the condition and before administering any common cancer treatment.

2. Environmental factors
The presence of harmful chemicals can also increase the chances of cancer. Passive smoking and exposure to harmful chemicals like asbestos and benzene are some of the important factors responsible for cancer.

3. Lifestyle factors
Smokers and alcoholics are at a high risk of developing cancer. Additionally, this disease can also occur in people who are exposed to the sun more often and those suffering from obesity. Many forms of cancer cannot be detected until they reach an advanced stage. As a result, they are diagnosed late and additional treatment options are administered for complete recovery. One should have a healthy lifestyle by following a balanced diet and using sunscreen when out and about. Additionally, smoking should be avoided as much as possible.

4. Viruses responsible for cancer
Hepatitis and herpes virus that causes inflammation of the throat lymphoid are some of the important viruses known to be possible risk factors for cancer. These viruses make the immune system weak, leaving your body vulnerable to diseases.

5. Mutation of DNA
The life cycle of a cell consists of its maturity, death, and the replacement of new cells with the old ones. However, due to mutation, the normal cell life gets interrupted, leading to cancer. When the mutation of genes occurs, it causes uncontrolled rapid growth and division of cells. Additionally, a mutation in the tumor suppressor gene allows the cancer cells to continue growing and get accumulated. This is quite common in cancer; however, other forms of mutation of genes can also cause cancer.

Mutation of genes can be caused due to various reasons. It could happen when a child inherits the genes from his/her parents at birth; however, this constitutes a very smaller percentage of cancer patients. Secondly, factors such as exposure to radiation, smoking, cancer-causing chemicals such as carcinogens, chronic inflammation, and obesity can also lead to the development of cancer.

It is important to be aware of the various risk factors and causes associated with cancer so that adequate preventive measures can be taken.
