So what is mesothelioma?

According to Wikipedia this is the definition of mesothelioma:

Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart, the pericardium (a sac that surrounds the heart) or tunica vaginalis.

Mesothelioma is linked with the inhalation or swallowing of asbestose, thus people in certain occupations are more liable to develope mesothelioma along with other diseases caused by asbestose such as asbestosis (which is a chroinic lung diseas) and lung cancer.

Mesothelioma can occur in other areas than the lungs such as the pericardium (the sac lining your heard) and the peritonium (the one lining abdominal viscera).

Symptoms and Signs:
The signs and symptoms vary acording to the site of the disease, but symptoms begin to appear after 10-20 years of exposure to asbestose, symptoms of pleura mesothelioma (mesothelioma in the outer lining of the lungs) include:

• Shortness of breath.
• Pain in the chest.
• Fatigue.
• Cough with or without blood.
• wheezes.

As the symptoms are vague and mostly general symptoms, the diagnosis must be done by X-ray which is suggestive. Diagnosis must be confirmed by biopsy.

Incidence of the disease:
Still defined as a rare disease although the rates of mesothelioma has increased in the past 20 years. 20,000 cases of mesothelioma are diagnosed in the U.S. every year.

Exposure to Asbestose:
Asbestose is now prohibited by laws in some countries. Soem industries where Asbestose is used include : Cement, brake lining, textiles and insulation of roofs, buildings. The workers at these industries are highly exposed to Asbestose.

Asbestosis and Mesothelioma had become a legal issue and a source of many court cases and compensations have been paid to large numbers of people affected by Asbestose exposure.

Smoking and excercise

Introduction:

Smoking and excercise seem to be two irrelative or even opposite words as smoking have a bad impact on your fitness and health. That's what you discover after 10 minutes of running or playing sports, you feel shortness of breath and air seems to be shy to enter your lungs, your heart isn't like a few years ago, you feel older.

Well, first let's agree on something: Excercise is of great value and importance to improve your health no matter if you are a smoker or non-smoker. It's obvious that non-smokers will have great benifits of excercise. It's good for your shape, your health, it strngthens your muscles, your immunity and your mood.

What about smokers? Let's try to explain how smoking affects your body first.

Cigarette smoke contains three substances : Nicotine, Carbon monoxide (CO) and Tar. Simply, smoking decreases the oxygen reaching your tissues, your muscles and your body. CO is responsible for this action as it binds to haemoglobin and limit it's Oxygen binding capacity, thus depriving your tissues (and your heart) from oxygen.

Your heart tries to work harder to compensate the oxygen deficiency (remember that your heart itself isn't receiving enough oxygen, so it's a huge load on it).Smoking also stiffens and clogs your blood vessels, thus increasing the risk of atherosclerosis in younger age. Nicotine also raises your blood pressure and increases your heart rate too, making things worse! And it's also responsible for the habituation and psychic dependence. While tar contributes to cancer occurance.

Excercise (for smokers and non) will strengthen your muscles (including the heart, which is a muscle!). It improves your respiration and oxygen delivery to the tissues.

Smoking and Excercise :
Excercise will also lower your blood pressure and lower your average heart rate (during rest) and decreases bad cholesterol in the blood protecting you from astherosclerosis, angina, infarction and coronary heart diseases. Excercise together with healthy food will also make your blood vessels stronger and protect you from a big list of cardiovascular diseases.


So, for smokers, excercise strengthens your heart so it can withstand the serious effect of smoking on it for a longer period. It doesn't cancel the effect of smoking and it can't. But it improves the condition of your heart, your cardiovascular system and your body in general, providing a more powerful enemy for smoking.

The most important part is the decision to start excercise, then to continue excercising. Doctors recommend 30 minutes of practice 3 times weekly. Walking, running, swimming, soccer playing tennis or any other type of working out will be good for you according to your age and health status. Start with what's easiest to you and by time you can increase the duration and the violence of excercise later on.
