Characteristics of Cancer

Despite the fact there are several hundred different types of cancer, it is still possible to list certain general characteristics. Cancer is a cellular disorder, and so these general characteristics pertain to cancer cells.

First, cancer cells experience uncontrolled and disorganized growth. Normal cells only divide about 50 (fifty) times before they die, but cancer cells enter the cycle of dividing and reproducing, over and over again and never differentiate. In tissue cultures raised in labs, cancer cells lack the contact inhibition exhibited by normal healthy cells. This means, normal healthy cells stop reproducing when they contact each other, or the sides of a culture bowl. Normal cells in a tissue culture grow in only one layer because they adhere to the glass bowl and stop dividing once they make contact with their neighbors. Cancer cells have lost all restraint and grow in multiple layers, most likely because of cell surface changes. In the body, a cancer cell divides to form a growth, or tumor, that invades and destroys neighboring healthy tissue. This new growth, termed neoplasia, is made up of cells that are disorganized, a condition termed anaplasia. The cells are disorganized because they don't differentiate into the tissue of the organ and they never fulfill the function of the organ. To support their growth, cancer cells release a growth factor that causes neighboring blood vessels to branch into the cancer tissue. This phenomenon has been termed vascularization, and some modes of treatment are aimed at preventing vascularization from occurring.

Second, Cancer cells detach from the tumour and spread around the body. To accomplish this, the cells often must make their way across a basement membrane and into a blood vessel or lymphatic vessel. It's been discovered that cancer cells have receptors that allow them to adhere to basement membranes; they also produce proteolytic enzymes that egrade the membrane and allow them to invade the underlying tissues. Cancer cells also tend to be motile. This may be associated with a disorganized internal cytoskeleton and their lack of intact micro filament bundles.
After traveling through the blood or lymph system, cancer cells start new tumor elsewhere in the body. This process is called metastasis.

If the original tumor is found before metastasis has occurred, the chances of sure are greatly increased. This is the rationale for early detection of cancer. In fact, sometimes a person isn't even considered to have cancer unless metastasis has occurred. Benign tuners are those that remain in one place; malignant tumors are those that metastasize.

1. Cancer cells do not have a Hayflick limit and can reproduce an unlimited number of times.
2. Cancer does not support normal body function.
3. Cancer is not stable as to size or location in the body.
4. Cancer will cause death eventually if the person's normal life span is longer than the time it take the cancer to become lethal.

There are SEVEN warning signs:

Change in Bowel or bladder habits
A sore that does not heal
Unusual bleeding or discharge
Thickening or lump in breast or elsewhere
Indigestion or difficulty in swallowing
Obvious change in wart or mole
Nagging cough or hoarseness


Characteristics of cancer?

There is no built-in limit to the SIZE of the growth (it doesn't know when to stop growing, as does normal tissue)

It often keeps its own temperature --it's hotter or cooler than surrounding tissue

It encourages the growth of capillaries to feed itself

It is generally not painful in its early stages

1. It is unpredictable to humans.
2. It has a different cause in every person.
3. It has many causes on the physical, mental and emotional, and even the Soul plane in each case.
4. You cannot heal it by tackling the symptoms. Remission is possible only by tapping into the cause, whilst healing means addressing the cause.
