Cause and Treatment for Cancer

Cancer gives no signs or symptoms that exclusively explain the nature of disease. But however, if you have any of the symptoms mentioned below, you should consult your doctor/cancer specialist as soon as possible.
Here are some symptoms of common cancer:
*Continual Cough or blood tinged saliva- These could be symptoms of cancer in the head, lung (bronchitis) or neck. Even a general cough can become a symptom of cancer if it lasts for more than a month. If that is the case, you should consult your doctor immediately.

* Changes in bowel habits- If you observe changes in your bowel movement or feel abnormality even after you have had a bowel movement should see a doctor.

* Blood in stools- A doctor must always investigate the blood in the stools. These can be observed through X-rays. But sometimes, when the source is known, these steps may not be necessary.

*Unexplained anemia- Anemia is a condition when the actual number of RBCs (Red Blood Cells) is lower than the desired number. Your doctor must investigate anemia also.
Anemia can be caused my many cancers, but the bowel cancer can cause iron deficiency. Your upper and lower intestinal tracts should be either evaluated by endoscopy or x-rays.

* Breast discharge or breast lump-All breast lumps need to be investigated thoroughly. A negative mammogram isn't sufficient to evaluate breast lumps. Generally, diagnosis requires biopsy or needle aspiration. Most of these forms of discharges and lumps may be causes of cancer, so if there is blood discharge from only one nipple, then it must be evaluated as soon as possible.

* Testicle lumps- Most of the men having cancer have uncomfortable or painless lump in their testicles. Some may even have enlarged testicles. The lumps and other conditions like swollen and infectious veins need to be continuously evaluated.

Cancer is caused by several ways. Sometimes, doctors have to battle the disease using several methods at once, and sometimes they use one method step wise of sequentially.

Cancer can be treated by a number of ways, thanks to improvement and success of modern treatments. There are basically four method of treatment of cancer. Chemotherapy, surgery, radiation therapy and biological therapy. In some cases, clinical trials may prove effective but everything depends on the type of cancer the person suffers from. There are other ways of treatment also which are not approved by the FDA and which are often given in countries other than USA.

When initially you’re diagnosed with cancer, the specialist/doctor will explain you how he will go with the treatment processes. But before that, he may also give you the treatment options. Generally a good doctor always gives you the best treatment which is based on the type of cancer you’re suffering from. Along with the treatment options, he or she will also give you details on how far its spread and the treatment duration etc.

But everything depends on your decision which usually depends on doctor’s opinion, alternative methods, information, treatment process and details gathered from specialists.

The actual goal of the treatment process is the complete removal of cancer without any adverse or side effects to the body. But the effect is often limited in the case of radiation therapy or by surgery due to toxicity of other tissues in the system. In fact, radiation can often lead to damage of normal tissues. Till date, there hasn’t been any 100 % effective cure for cancer, as cancer is a class of diseases. Radiation therapy is used to destroy cancer cells with X-rays or particles from radioactive elements such as cobalt 60.
