In this article, I discuss symptoms of cancer, causes of cancer, tests, treatment of cancer, types of cancer.It is Cancer research article.
What is Cancer?:
Cancer is the abnormal and uncontrol growth of the cell in the body. Cancer can start from any part of the body. Normally the cells divided to form new cells in the body as they need. The old or damaged cells are replaced by new cells.
In the case of cancer, this orderly process breaks down. The cells don’t die when they are old or damaged and new cells generated when they are not needed. These unwanted cells divided without stopping and may for growths called a tumor.
Tobacco and smoking are dangerous. There are about 70 known chemicals in tobacco which may cause cancer. These chemicals are called carcinogens.
Genetically modified food, microwave popcorn, canned food, grilled red meat,
Refined Sugar, Smoked Foods, Soda and Carbonated Beverages, White Flour, Farmed Fish: Hydrogenated Oils may cause cancer when it takes in an excess amount.
Ultraviolet radiation, X-ray and gamma-ray, Radon, microwaves, radio waves, power line, Electrical device, cellular phone, cellular phone tower etc. and some other modern technology may cause cancer in human body.
Overweight or obese can raise the risk for certain types of cancer. Excessive intake and use of alcohol increase the risk of cancer. There is some infectious agent such as bacteria, virus etc may lead to cancer in the body.
Types of Cancer:
There is a lot of cancer type. The most common type of cancers is as follows.
Anal cancer, Bladder cancer, Bone cancer, Bowel cancer, Brain cancer, Breast cancer, Breast cancer in men, Cancer of unknown primary, Cervical cancer, Head and neck cancer, Kidney cancer, Leukemia, Liver cancer, Lung cancer, Lymphoma,Mesothelioma,Melanoma,Mouth Myeloma, Oesophageal cancer,Ovarian cancer,Pancreatic cancer,Prostate cancer,Skin cancer,Stomach cancer,Testicular cancer,Throat cancer,Thyroid cancer,Uterine cancer,Vaginal cancer,Vulvar cancer etc.
How cancer spreads
The procedure of cancer cell spread is called metastasis.In this procedure, the cancer cell spread from where they started to other parts of the body and the can grow new cancer cell or tumor in the new place.
Cancer can spread in three ways. At first, the cancer cells spread to surrounding cells. and grows up. Then through the bloodstream, the notorious cells travel in the new location of the body. The cancer cells also spread through the lymphatic channel. The cancer cells first break away from the tumor and travel through lymph vessels and nodes to other parts of the body.
What is prostate cancer?
Cancer which developed in prostate gland is called prostate cancer.It is known as adenocarcinoma.it is a very slowly progressive disease.Prostate cancer starts with tiny alteration in the shape and size often prostate gland cells.Cancer cell move from one part to another part of the prostate gland
Prostate cancer symptoms:
The symptoms of prostate cancer as follows
- The patient urinate more often
- He may find hard to start urinating.
- He may find hard to keep urinating once he has started.
- The may be blood in urine.
- Urination may be painful.
What is breast cancer:
Breast cancer means cancer which develops in breast cell. Usually, it starts from the inner lining of milk ducts or the lobules. When it becomes malignant it may spread in the whole body.
Why breast cancer:
There are a lot of cause for cancer.
When a woman getting older, her risk of developing breast cancer is increased. The woman carrying BRCA1 andBRCA2 genes have a considerably higher risk of developing breast cancer. If the woman with more dense breast tissue has a greater chance of developing breast cancer. When period started earlier or entered menopause later than usual have a higher risk of developing breast cancer.
Postmenopausal obesity in a woman may lead to higher risk of developing breast cancer. The woman taking alcohol regularly have a high risk of breast cancer. Radiation exposure may raise a woman’s risk of developing breast cancer. Hormone replaces therapy may raise the risk of breast cancer in women.
Breast cancer stages:
The stages of breast cancer are usually expressed as a number on a scale 0 through IV.Stege 0 is described as non-invasive cancer that remains within their original location and stage IV describes invasive cancer that has spread outside the breast to other parts of the body.
It is a common and locally destructive carcinogenic growth of the skin.Normally it started from the cells that line up along the membrane that separates the superficial layer of skin from the deeper layers
Skin cancer can be classified into the major types. these are basal cell carcinoma, squamous cell carcinoma and last one is called melanoma which originated from the pigment-producing cells. It is less common but more dangerous than first two.
Cervical cancer is the cancer of cervix which is the lower part of the uterus. Cancer starts from the transformation zone of the cervix. The time requirement from pre-cervical cancer. The most common type of cervical cancer is squamous cell carcinoma and adenocarcinoma.
Liver cancer is a condition where normal cells in the liver become abnormal in appearance and behavior. The cells destroy the adjacent normal tissues and can spread to another part of the liver and to organs outside the life.
Thyroid cancer is the cancer of thyroid gland which is uncommon.The symptoms of thyroid cancer include lumps or swelling in your neck. It is more common.
Bone cancer is the malignant tumor of the bone that destroys normal bone tissue.In primary bone cancer, the malignant tumor found in bone but it spread in the whole body in malignant condition.
About Stomach cancer:
Stomach cancer starts in the inner lining of the stomach.These also called gastric cancer.it grows slowly over many years.
Symptoms of Stomach cancer:
In the early stage, indigestion, feeling bloated after eating a meal, heartburn, slight nausea, loss of appetite is found.
In a later stage, the symptoms include stomach pain, blood in stool, vomiting, weight loss for no cause.
Brain cancer starts with a primary brain tumor in brain and secondary tumors which may spread in another part of the body.There is about 40 major type of brain tumor which is classified into group—Benign and malignant.Headaches are the first symptoms of brain tumor.It may be mild, sever, persistence or come and go.All a headache is no brain tumor so nothing to be worried. High radiation may cause tumor in the brain.Some brain and spinal cord tumors are common in people with certain inherited or genetic condition.
