"Mesothelioma" is the term used to describe a cancerous tumor that involves the mesothelial cells of an organ. Mesothelial cells are cells that form a protective lining over the lungs, heart and abdominal organs. The most common type of mesothelioma is pleural mesothelioma. The pleura is a thin membrane found between the lungs and the chest cavity. It provides a lubricated surface so that the lungs do not rub and chafe against the chest walls.What causes it?
Virtually all cases of mesothelioma are related to inhaling of asbestos fibers. There are about 3,000 cases per year (mostly men over the age of 40) and there will be about 300,000 cases before 2030. Mesothelioma usually spreads rapidly through the mesothelial cells to the heart and abdominal organs. The life span is typically 24 months after diagnosis, but it depends on what stage the cancer is detected, the health of the patient and other factors.Although asbestos exposure causes mesothelioma, it has a latency period after exposure that could last 15 to 50 years. This means that someone who worked in a factory with asbestos 40 years ago could be developing mesothelioma now. Anyone who knows they were exposed to loose asbestos fibers should be tested regularly for mesothelioma.
DiagnosisThe onset of mesothelioma is usually very slow. The first symptom is a constant pain in the chest. This pain is later accompanies by difficulty breathing due to an accumulation of fluid in the chest. Other symptoms include coughing, fever and weight loss. Mesothelioma can be diagnosed by your doctor with a chest CT-scan.
Prognosis (the outcome)Mesothelioma advances in 4 stages:Stage I - the tumor is limited to the area of the lining of the lung and usually limited to only one side of the chest.Stage II - the tumor extends to other organs within the chest cavity, such as the heart or lymph nodes in the chest.Stage III - the tumor expands to the other side of the chest or it spreads into the abdominal organs. The lymph nodes outside the chest are affected.Stage IV -the cancer spreads to different parts of the body far outside the chest area (liver, brain, bone, etc...).
Mesothelioma is an extremely deadly disease. The average survival time is about one year from date of diagnosis. About 20% of patients who find their cancer early and treat it aggressively will reach the five-year mark.

Acne treatment
Blackheads are mild and noninflammatory in nature and therefore it is you who could take care of these small zits by a few very simple precautionary steps. Grow a habit of cleansing your face twice a day with warm water and mild soap. This would help removing the extra oil from your skin surface along with the accumulated dead skin cells. Never pick or pop the zits, no matter how impulsive you feel to do so. If you really need to do it then perfectly disinfect your hands before touching the affected area or visit some skin expert. They often do the same job by using sterilized instruments specially designed to serve this purpose solely. Blackhead removal is rather less risky than other moderate and severe type of acne. Still it is highly recommended not to go for self-extraction unless you have enough confidence in performing this job.
Blackheads, the apparently mild type of acne, are often found to bear this attribute of showing up here and there, almost all over the face. They are also known as open comedones and appear usually on oily skin. They look like small black spots or dents on the skin surface, often hard to touch and noninflammatory in nature. These days natural or home remedies for pimples and zits have won the hearts of many acne victims due to their simplicity and harmless yet effective outcome. For instance, using an almond or oatmeal face mask for better cleansing has proven to be very effective. Mix any of them with rose water to make a soft paste and rub all over the face, leave for 15 minutes and then rinse with cold water. Honey is another beneficial acne remedy. Apply sufficient amount with your fingertip on the affected areas and leave for 15 minutes, then wash with water or you can use pure lemon juice 2 to 3 times a day. A regular use for a few weeks would definitely show a visible change. Proper exfoliation of the skin is a very essential matter in preventing blackheads. Use some natural skin exfoliator for this purpose.
Why blackheads form? In order to find the answer we need to get clear about how acne is formed. The basic reason behind acne formation is excessive secretion of sebum or body oil by the sebaceous glands embedded deep within the skin surface. These oil glands are attached with the hair follicles through which the discharged body oil travels up to the skin surface. The amount of oil secretion is governed to a large extent by androgens or the male hormones present within human body irrespective of gender. When the sebaceous glands get stirred up by the oversecretion of androgen, they start releasing a greater amount of oil. The dead skin cells around the hair follicle lining stick up with this surplus oil and form a cluster clogging the hair follicles, giving rise to comedonal formation. Typically in case of blackheads, these comedones are partially open and the accumulated plug inside the pore remains under air contact due to which they grow darker or almost black in color.

Works overtime the change to impair the lady health
•Working long hours has a greater negative impact on women than men because it makes them more likely to smoke, drink coffee and eat unhealthy food.
Both sexes consume less alcohol if they spend more time working, researchers said, but toiling extra hours makes women crave unhealthy snacks.
"Women who work long hours eat more high-fat and high-sugar snacks, exercise less, drink more caffeine and, if smokers, smoke more than their male colleagues," said Dr. Daryl O'Connor, a researcher at Britain's Leeds University.
"For men, working longer hours has no negative impact on exercise, caffeine intake or smoking," O'Connor said in a statement released by the Economic and Social Research Council, which funded his study.
O'Connor's team of scientists were studying the impact of stress on eating habits. They looked at what causes stress at home and at work and how people react to it.
•The results show that stressful events such as making a presentation, a meeting with the boss or missing a deadline were linked to eating more between-meal snacks and fewer or smaller portions of fruits and vegetables.
"Stress disrupts people's normal eating habits," he said.
The people who were most vulnerable were so-called emotional eaters. "These individuals have higher levels of vulnerability and tend to turn to food as an escape from self-awareness,"
O'Connor said. "When they feel anxious or emotionally aroused or negative about themselves, they try to avoid these negative feelings by turning their attention to food."
