What are the different signs , symptoms and stages of cancer ?
Cancer signs and symptoms
All of the cancer symptoms metastasis depend on the location of the tumor , When the cancer begins , It invariably produces no symptoms , The signs and symptoms only appear as the mass continues to grow or ulcerates , The mass effects from the lung cancer can cause the blockage of the bronchus resulting in the cough or the pneumonia .
You have to know that the esophageal cancer can cause narrowing of the esophagus , So , it is difficult or painful to swallow , and the colorectal cancer may cause the narrowing or blockages in the bowel , resulting in changes in the bowel habits , The masses in the breasts or the testicles may be easily felt , Ulceration can cause bleeding that .
It is very important to know that if it occurs in the lung , It will lead to coughing up the blood , in the bowels to the anemia or the rectal bleeding , in the bladder to the blood in the urine , and in the uterus to the vaginal bleeding , Although the localized pain may occur in the advanced cancer , the initial swelling is usually painless , Some cancers can cause a buildup of fluid within the chest or abdomen .
You have to know that the general symptoms occur due to the distant effects of the cancer such as the unintentional weight loss , the fever , being excessively tired , and changes in the skin , The Hodgkin disease , the leukemias , and the cancers of the liver or kidney can cause a persistent fever of unknown origin , Some cancers may cause specific groups of systemic symptoms , termed paraneoplastic phenomena such as the appearance of myasthenia gravis in thymoma and clubbing in lung cancer .
The different stages of cancer
There is limitless number of cell divisions , There is the promoting blood vessel construction , There is the tissue invasion and the metastases formation , The changing from the normal cells to the cells that can form the detectable mass to the outright cancer involves many steps known as the malignant progression .
The stage of cancer means the stage that the cancer was at when it was first diagnosed , The stage is very important to prognosis , prediction of the cancer’s effect on the person who has it ,The higher the stage, the worse the cancer’s effect on the person who has it .
In stage 0 ( situ cancer ) , The cell which becomes the cancer cell usually does so in the company of other similar cells but not always , it can produce the tumor in that tissue , in a way that poses little or no threat to life , It is called the situ cancer , The cancer in the position where it started , And some cancers never go beyond this early stage .
In stage 1 ( localised cancer ) , In the next stage , the cancer cells gain the ability to pass through the basement membrane in which the cancer began , and to invade the neighbouring tissue , that invasion is the serious step as it indicates that the growing cancer cells may threaten the life , It is said to be in the localised stage , the cancer is relatively small and contained within the organ it started in .
You have to know that in stage 2 and 3 ( the regional spread ) , When the cancer cell has invaded , The common next step is for one of its daughter cells to invade through the lymph vessel ( The vessel such as the blood vessel that carries the clear fluid called the lymph that is all the time exuding into the tissue from our blood capillaries , back to the blood stream ) .
It is very important to know that on the way to the blood stream , the cancer cell can get caught in the lymph node , one of the powerhouses of the body’s immune system ,There it might provoke the immune response against it that can go on to destroy it and the other cancer cells , though , it divides and forms the lump in the lymph node , This stage is known as the regional spread .
In stage 4 ( the distant spread ) , The next step can be quite varied , The cells from the lump in the lymph node can spread through the lymph vessels to the distant lymph nodes or into the blood stream , Or the cells from the original lump can invade the capillary and enter the blood stream that way , when the cancer cells can go just about anywhere in the body , form the new colonies and spread further , It is the stage of the distant spread .
