Cancer is one of the leading killer diseases in the world today. Different types of cancer with varying symptoms exist. It is essential to understand the causes and symptoms of cancer to seek medical attention in good time before the disease progresses beyond manageable levels. Being knowledgeable about cancer also reduces the risk of contracting the disease.
Causes of Cancer
Cancer is caused by DNA mutation that occurs within cells. However, this is the simplest explanation. It is necessary to understand exactly what can trigger changes to DNA within body cells. These are some of the common causes of cancer:
- Poor eating habits and lack of exercise – People that eat foods with a high amount of cholesterol are more likely to suffer from cancer compared to those who eat food with low amounts of cholesterol. Fast foods such as fries and burger have high amounts of cholesterol which make them unhealthy and likely to cause cancer. Lack of exercise accompanied by poor eating habits is also a major cause of cancer. A sedentary lifestyle is seen as one of the key reasons why cancer is such a major threat to the society today.
- Exposure to Radiation – Radiation exposure can also cause cancer and hence the reason why areas close to nuclear disasters are usually rendered inhabitable for several years.
- Hereditary causes – Some people are predisposed to cancer as a result of their genetic composition. A person born into a lineage with a history of cancer is more likely to contract the disease compared to someone from a lineage without a history of cancer.
Cancer signs and symptoms vary depending on the type of cancer and the part of the body that is affected by the disease. Common symptoms of cancer include general body fatigue and weakness, a lump that can be felt under the skin, drastic changes in weight, persistent indigestion, skin changes, unexplained bruising or bleeding, and persistent and unexplained joint or muscle pain.
It is important to go for regular medical checkups because some patients fail to notice any of the mentioned symptoms. This is especially important for individuals from families with a history of cancer.
Treatment for Cancer
It is easier to treat cancer when it is discovered early enough before it spreads to the other parts of the body. There are different types of treatment and remedies for cancer that are available depending on the type and spread of the disease. One of the most common types of treatment is surgery. This is done to remove as many cancerous cells from the body as possible. The other form of treatment is chemotherapy which uses drugs to eliminate the cancer cells.
Cancer is a stubborn disease. It is, therefore, important for patients to take utmost care to avoid a recurrence of the disease.
