What is Cancer?
Cancer is the term used to describe uncontrolled cell growth. Cancer can strike almost anywhere in the human body because every part and every organ is made from millions of cells. The division and development of cells is an extremely delicate procedure and any interruption in the process can cause an abnormal level of cell growth. If the growth becomes very large it is called a tumour.
Benign and malignant are the two types of cancerous tumours. The benign type is safe and does not cause harm to the patient or spread, and they can easily be removed. Malignant tumours are often serious and can spread to other organs and body parts, and if left untreated are generally fatal. The malignant type is what the term cancer generally refers to.
What Are The Causes Of Cancer?
No one really knows what the causes of cancer are, although scientists, doctors and specialists have a good idea of things that increase the risk of cancer. The risks known today include things like viruses and exposure to substances known as carcinogens. A report published in 2002 suggested that as many as one fifth of cancer cases were caused by viruses.
Cancer is reportedly common in patients with a weak immune system, including people suffering from HIV.
There are also various other things that scientists believe to increase the risk of cancer, such as smoking which is known to be related to lung cancer , and patients diagnosed with skin cancer seem to consistently have had prolonged exposure to UV radiation either from sunbathing, spending much of their time in direct sunlight and using sun beds. Carcinogens including certain pesticides have also been linked to cancer. Cancer has also been found to be genetic and patients with close relatives who have had cancer are more likely to develop it themselves.
There are treatments available to help reduce cancerous tumours which we will go into more detail over in the treatments section. Many of the drugs are available from Canadian pharmacies and online RX drug traders.
Cancer Symptoms
Symptoms are very differing depending on type of cancer that a patient has. General common symptoms are weariness and exhaustion, sudden weight loss and pain. There are other symptoms which are more specific to cancers affecting different parts of the body, such as headaches in patients who have a brain tumour.
How Common Is Cancer?
The World Health Organization forecasts that 10 years from now there will be15 million new instances of cancer. They also said that in 2000, over 10% of deaths across the globe were caused by cancer and if it continues this way, cancer could become the leading cause of death by 2010. However the WHO also said that these deaths would easily be reduced by earlier and more effective screening as well as people taking responsibility for their health and refraining from smoking, eating healthily and more exercise.
Treatment of Cancer
There are four ways to treat cancer and these are surgery to remove a tumour, chemotherapy, radiation therapy, and immunotherapy. The type of cancer determines the type of treatment required.
There are RX drugs available from online Canadian pharmacies which aid a patient who is undergoing cancer therapy. Examples are Arimidex 1mg, a chemotherapy drug to treat breast cancer, and Velcade which is designed to help fight myeloma which is a cancer of the blood.
RX and prescription drugs are available at low prices from Canada drugs online suppliers, and can be purchased conveniently over the internet. Your mail order drugs will arrive in the mail and you don't have to go anywhere to find them.
