Warning Signs of Cancer

A disease which causes development and uncontrollable growth of abnormal cells in the body is referred to as cancer. It is capable of destroying healthy cells and can spread in the body at an alarming rate.  

Even though cancer kills the second most number of people in the US, advancement made in treatments have significantly reduced the number of deaths caused by this disease. Finding the cause of cancer is always difficult, but if it is caught early, then it can be treated much more effectively using surgery. This is why it is important to know the symptoms of cancer.

1.     Changes in Skin

Skin changes are among the warning signs of skin cancers. Visible changes in the skin can also be produced by some other types of cancers as well. A rapid rise in hair production, constant itching, reddening of the skin, yellowing of the eyes or the skin and turning to darker color are all the signs of cancer.

2.     Fever

Cancers are usually accompanied with fever. You are going to have a fever if the cancer is affecting your immune system. Most of the time the cancer patient will have a fever after the cancer has metastasized to other parts of one's body. In some rare cases, a fever may be an early indication of blood cancers like lymphoma or leukemia. 

3.     Fatigue

Fatigue can be caused by the unusual blood loss that happens in the case of colon or stomach cancers. Moreover, it is also considered as an early symptom of leukemia. In most cases, the patient starts feeling more fatigued and tired during the later stages of cancer.

4.     Pain

Pain felt in the back can be a sign of colon, ovarian or rectum cancer, while having a severe headache that does not respond to pain medication is indicative of brain cancer. Patients suffering from testicular or bone cancer might start complaining of having pain in their early stages.

5.     Weight Loss

Loss of body weight that occurs without reason is considered as the most common early symptoms of cancer. Cancer patients are bound to lose weight at some point during their disease. If you lose 10 pounds or more bodyweight, then you might have pancreatic, lung, esophageal or stomach cancer.

When to See a Doctor

Although the abovementioned symptoms are the most common symptoms found among cancer patients, they are not the only signs of cancer. It is imperative that you report any kind of abnormality that you feel in your body to a doctor if you keep on noticing it for a long time. This will help you in figuring out what is wrong with you and in eliminating the possibility of cancer.
