Your Chances Of Surviving Cancer

Your Chances Of Surviving Cancer



Understanding cancer is​ not difficult if​ we start looking at​ cancer from the​ inside. the​ cancer starts in​ the​ cells, and​ Cells can break off from a​ malignant tumour and​ start to​ grow in​ another part of​ the​ body, this is​ known as​ a​ secondary tumour. Cells in​ these tumors are abnormal and​ divide without control or​ order. They can invade and​ damage nearby tissues and​ organs. Cells grow by dividing in​ half, such that one cell will become two, and​ two become four (these new cells are called daughter cells), etc . Normally, there are very strict rules as​ to​ when a​ cell can grow or​ not.

Cells in​ benign tumors do not spread to​ other parts of​ the​ body. Most important, benign tumors are rarely a​ threat to​ life. Cells deprived of​ oxygen die and​ decay, which is​ why some cancers have an​ odor. the​ term for​ this new blood vessel growth is​ angiogenesis.

Obviously as​ you may know already, malignant tumors are cancerous. These tumors contain cells that divide and​ grow without order. Malignant tumors (cancers) can spread to​ other tissues or​ organs nearby or​ to​ other parts of​ the​ body. This is​ called metastasis . Malignant tumors are tumors that are capable of​ spreading by invasion and​ metastasis. By definition, the​ term "cancer" applies only to​ malignant tumors.Malignant means that the​ disease, if​ not treated, can progress and​ lead to​ death. Malignant tumors are cancer. Cancer cells can invade and​ damage tissues and​ organs near the​ tumor. Malignant tissues can invade and​ damage other tissues and​ organs. Cancer cells can then break away from the​ tumour and​ enter the​ bloodstream or​ lymphatic system, spreading the​ cancer to​ other parts of​ the​ body.

the​ serious part of​ this is​ that malignant tumours metastasize to​ other organs of​ the​ body and​ continue developing unlimitedly.

In the​ other hand Benign tumors can often be removed by surgery, and​ they are not likely to​ return. Some tumors of​ the​ testicle are benign, but most are not. Benign tumors are not usually life threatening. Benign tumors, although they may cause some health problems depending on their size and​ location, are not life-threatening.

Benign (noncancerous) tumors can also grow anywhere in​ your mouth. Benign tumors are well-differentiated ---in other words, they differ only slightly in​ appearance and​ behavior from their tissue of​ origin. These tumors are slow growing and​ noninvasive, do not spread throughout the​ body, and​ will often have a​ fibrous tissue capsule around them.

Treatments are related to​ a​ particular cancer’s usual behavior. for​ a​ cancer that is​ aggressive locally (where it​ is​ first detected), local treatments such as​ surgery, radiation therapy, and​ photodynamic therapy may be used. Treatment depends on the​ kind of​ treatment the​ patient had when first treated. if​ the​ patient had surgery alone, the​ patient may have surgery again or​ radiation therapy.

Radiation therapy destroys or​ damages cancer cells by targeting high energy x-rays to​ the​ tissues. Radiation therapy is​ usually painless and​ is​ provided in​ an​ out patient setting. Radiation is​ a​ special kind of​ energy carried by waves or​ a​ stream of​ particles originating from radioactive substances and​ delivered by special machines. These radioactive x-rays or​ gamma rays can penetrate the​ cell wall and​ damage the​ nucleus of​ the​ cell which prevents growth and​ division of​ cells.
