Cancer is a disease which is characterized by abnormal cell growth. It usually spreads to other parts of the body. It is the 3rd most common disease and responsible for a large number of deaths all over the world. Possible signs of cancer include a lump, prolonged cough, abnormal bleeding and a change in bowel movements. Besides these, there can be other reasons also for cancer. Cancer cause can be known from studies carried around the world.
First of all, there are many causes of cancer. Tobacco is considered as the main cause of cancer in most of the death in cancer. Secondly, other reasons like poor diet, lack of physical activity, excessive drinking of alcohol obesity are also responsible. Therefore we should not use them. Similarly, many infections, environmental pollutants, exposure to ionizing radiation also causes cancer. On the other hand in developing worlds infections such as Helicobacter pylori, hepatitis B, hepatitis C, Epstein- Barr virus, HIV, human papillomavirus infection are the main causes of cancer. Meanwhile, genetic defects acquired from parents also are the main reason for cancer.
However, there is a method by which we prevent cancer. Firstly by not smoking, maintaining a healthy weight and eating plenty of vegetables could prevent cancer. Secondly, fruits and whole grains, avoiding alcohol consumption can help to prevent cancer. Further avoiding processed food, red meat and avoiding too much exposure to sunlight can help prevent cancer. To sum up we should take care of our eating habits.
Most of the cancers are recognized because of the appearance of signs or symptoms or through screening. For example, the examination of a tissue sample by a pathologist also help in recognizing cancer. For instance, medical tests are conducted on patients to suspect cancer. On the other hand, most common tests are X-rays, blood tests, CT scans, and endoscopy. Other important tests are cytogenetics and immunohistochemistry. These tests give information about molecular changes. In conclusion, this test can identify cancer in its early stages.
There are many types of cancer. These are
The derivation comes from epithelial cells. During this stage, they mostly occur in the breast, lungs, prostate, pancreas, and colon.
These generally arrive from connective tissue. These develop from cells originating in mesenchymal cells outside the bone marrow.
Lymphoma and Leukemia
These arrive from hematopoietic cells that leave the marrow and then mature in the lymph nodes and blood.
Germ cell tumor
They develop from pluripotent cells generally present in the testicle or the ovary.
Here the immature “precursor” cells or embryonic tissue plays the vital role.
Treatment Of Cancer Cause
There are various techniques for treating cancer. These include chemotherapy, radiation therapy, hormonal therapy, targeted therapy, and palliative care. They are the most effective treatments in cancer.
It includes the treatment of cancer using cytotoxic anti-neoplastic drugs. These act by killing cells that divide rapidly.
Radiation therapy involves the use of ionizing radiation to cure cancer. It works by damaging the DNA of cancerous tissue or killing it. Here mainly head and neck cancer taken care of.
The most commonly used methods for cancer is surgery. It is the method of removing cancer by removing the entire mass including the lymph nodes in the area.
It is the treatment that attempts to help the patient feel better. In this they work on physical, emotional, spiritual and psycho-social distress of the patient. Its primary goal is to improve the quality of life of the person.
It includes the immune system to fight cancer. Here antibodies plays the vital role to fight cancer.
It includes a high-intensity light to destroy the tumors or precancerous growth. Mostly it is expensive than the others. It is treated with Surgery, chemotherapy or radiation therapy.
