The awareness of the dangers of skin cancer, particularly melanoma, has doubtless increased. Still, the most fatal form of melanoma is frequently left undiagnosed in the fledging stages.

Nodular melanoma is the most serious and life threatening form of skin cancer, constituting around 35% of all thick melanoma cases. In comparison, the most general form of melanoma, the superficial spreading melanoma, is regularly diagnosed in its infancy and characteristically is a thin melanoma.

The dissimilarity between thick and thin melanomas is quite straightforward. Thin melanomas have a tendency to spread out over the top of the skin surface. Thick melanomas, on the other hand, are more penetrating and grow deeper into the skin.

Commonly, nodular melanoma is already invasive upon first diagnosis. This form of cancer is normally seen on arms, legs and upper torso of an elderly person. The scalp may be affected at any age.

This malignancy is characterized by a bump-like feature, generally black, but at times blue, white, gray, brown, red, tan or skin tone.

Nodular melanoma is far less common than any of the other sub-types. It accounts for only 15% of all melanoma cases. Reports suggest that this disease commonly affects people after the age of fifty. Medically, nodular melanoma appears as a consistent blue-red, blue-black or amelanotic nodule.

Nearly 5% of nodular melanomas do not have pigment. They are called amelanotic melanoma. The most affected areas for nodular melanoma are the head, neck and upper torso. It is important to remember that a nodular melanoma usually starts in normal skin, and not in an already existing lesion. Nodular melanomas are also characterized by rapid growth.

There are a few factors that lead to lung cancer. Some of the most common reasons are:

1. Cigarette smoking: It is a very common factor. There are people who are addicted to cigarette smoking and some even smoke two packs or more per day. Out of every seven people, at least one person would develop lung cancer. Folks who smoke about one pack of cigarettes per day are prone to this threat 25 times more than non-smokers. People who casually smoke are also not free from this, as they could also develop lung cancer.
Smoking damages the cells. The moment you quit smoking the damaged cells start repairing themselves and become healthy cells. So, it is advised to give up smoking altogether.

2. Secondhand smoking: it is also known as passive smoking because you tend to inhale smoke without actually holding a cigar or a pipe between your lips. The people who are exposed to this kind of smoking have 24% chances of developing lung cancer. About 3000 deaths are estimated in a year due to secondhand smoking.

Asbestos Exposure: Asbestos causes lung cancer and mesothelioma known as the cancer in the linings of the pleural sheet. It separates the silica fibers that are trapped in the tissues of the lungs. If you have been a smoker or if you smoke even now, then the possibility of contracting this disease is high. The risk is about 50 to 90 percent more than non-smokers.

Radon Gas: radon is a gas that is colorless and odorless that is released from decayed uranium. As per the analysis done by the U.S. Environmental Protection Agency, almost 15% of the homes are exposed to radon and every year about 15,000 to 22,000 deaths occur.

Air pollution: if you inhale polluted air for a long period of time then you are most likely to develop cancer. About 1% of the total lung cancer deaths are due to this problem.

Mesothelium cells serve the function of producing the lubricating fluid that enables the
body organs contained within their cavities to move and slide freely. The lungs will move
freely during the process of breathing. The mesothelium in the chest cavity covers the inner lining of the chest wall and is called parietal pleura. The lungs are also covered almost completely by mesothelium. This portion of the mesothelium covering the lungs proper is called parietal pleura. By their secretions the lungs move freely during inspiration and expiration.

The abdominal cavity has a similar configuration. The inner lining of the abdominal cavity is invested by mesothelium called the parietal peritoneum. The visceral peritoneum covers the surfaces of the intestines and other organs in the abdomen including liver and spleen. Some portions of the intestine are freely mobile and dangle on tissue pedicle called mesentery which is sandwiched on both surfaces by visceral peritoneum. Examples of these include most of the small intestine, transverse large intestine, sigmoid large intestine, and portions of the underbelly of the liver.

The intestines will move freely during digestion, the heart will move freely during its contracting functions, and the testicles will also freely
slide in the testicular cavity. The development of mesothelioma will therefore either destroy
the organs contained within these cavities by directly invading them or encase them restricting
their movements like a “boar constrictor” only very slowly. As you can imagine, when these
scenarios occur, the functions of the lungs, heart, and organs of the abdominal cavity will
be severely compromised leading to a variety of unpleasant and life threatnening effects or
symptoms of the disease and death.
