Cancer is a group of diseases that may cause almost any sign or symptom. The signs and symptoms will depend on where the cancer is, the size of the cancer, and how much it affects the nearby organs or structures. If a cancer spreads (metastasizes), then symptoms may appear in different parts of the body. As a cancer grows, it begins to push on nearby organs, blood vessels, and nerves. This pressure creates some of the signs and symptoms of cancer. If the cancer is in a critical area, such as certain parts of the brain, even the smallest tumor can cause early symptoms.
Wild cell growth turns into cancer when it is exposed to carcinogens (Cancer- causing substance) genetic defects, or viruses. A tumour is formed when cancer cells multiply large masses of tissue. In some cases tumours limit themselves to one spot in the body; some can be removed by surgery. These kinds of tumours may cause little harm and is termed benign. Hostile tumours are called malignant. The study of cancer is called oncology.
Why cancer has and is becoming more prevalent?
Over the last generation there has been vast difference between the way we use to live and how we are now living. I can almost say that we live in a different world. Technology has been increased by a large percentage. Smelter plants, environmental chemical, polluted air, microwaves, computers, utensils and a lot of foods are said to be cancerous to us. Meats that are harmonized (e.g. chicken), plants, vegetables, fruits etc. these are all things that should make us healthy, but instead it can be deadly to us. Because of the amount of hormones that are being injected into them, plants and trees are being sprayed with insecticide, fertilizers as though these liquids are water. Then they are being sold to groceries, farmers etc, for us to buy and eat.
Is there any cure for cancer?
Since cancer has been detected, no cure solution has ever been introduced. Various anti–cancer tablets and chemotherapy was put in place in order to control cancer cells. Cancer, AIDS and Sugar diabetes are the three major sicknesses that have no cure. Although there are things out there to help cancer. It is proven that more and more people are getting cancer. Women have become prone to Breast cancer for the past 3o years. United States had even poured out $30 billion to help find a solution to cure cancer.
Causes of Cancer
People get lung cancer most of the time from smoking tobacco which is said to have carcinogenic substance mainly known as tobacco smoke. Some carcinogens include certain chemicals, the Sun’s ultraviolet light, and radiation. Cancer can be formed by several viruses by altering the DNA of a host cell and converting the cell’s normal genes into cancer – causing genes, or oncogenes. Genetic factors – such as chromosomal abnormalities or the inheritance of faulty genes from a parent of fore parent. This could most likely cause these persons who inherit these genes can end up having cancer. People that are Down syndrome, a chromosomal abnormality are susceptible to leukaemia.
Names of Cancers
Lung Cancer, Bladder Cancer, Colon and Rectal Cancer, Breast Cancer, Endometrial Cancer, Kidney (Renal Cell) Cancer, Non- Hodgkin Lymphoma Pancreatic Cancer, Skin Cancer, Non-melanoma Thyroid Cancer, Prostrate Cancer, Leukemia, Bladder Cancer, Bone Cancer, Bile Duct Cancer, Brain Tumour, Appendix Cancer, Adrenocortical Carcinoma, Cervical Cancer, Childhood cancer, Eye Cancer, Gall Bladder Cancer, Kidney Cancer, Lip and oral Cancer, Liver Cancer, Mouth Cancer, Rectal Cancer, Salivary Cancer, Urethral Cancer, Vaginal Cancer, Vulvar Cancer
Treatments for cancer
Oncologists have been using Chemotherapy, or drug therapy to help cancer patience around the world. When cancer spreads to different parts of the body chemotherapy is used to help treat the cancer, before it gets worst. The immune system is weak when cancer spreads through the body. Therefore a treatment name immune enhancing drugs or antibodies are also used to help build back up the immune system and to destroy abnormal cells. There has been an anticancer drug that kills cancer cells while leaving the good ones alive. This drug was introduced in the spring of 2001. The drug, Gleevec has proven to work very strongly against chronic myelogenous leukaemia, leukaemia is one of the four main types of blood cancer.
