Mesothelioma: notifiable disease
Mesothelioma has been declared recently as disease notifiable. This term means that the doctor who diagnosed the disease in the patient must inform the health authorities. The objective of this decree is to better understand this rare type of cancer by identifying the causes.
A rare cancer
Mesothelioma is a cancer often located in the peritoneum. The National Cancer Institute (INCA) claims to have identified between 800 and 1200 cases of mesothelioma each year. These figures represent only 0.3% of all cancers .
Exposure to asbestos at work is the main cause of this cancer. It is good to know that asbestos is a highly toxic mineral used in building construction.
The objectives
The National Mesothelioma Surveillance uses this order to try to identify risk factors for mesothelioma other than asbestos exposure in order to strengthen their program of surveillance and prevention. Physicians must complete a form available at the INVS to report a case of mesothelioma.

Causes of Lung Cancer
The snuff smoking is the main cause in 90% of cases of lung cancer in both men and women. Decades ago, this tumor was much less common in women and it was featured it was more likely that was not related to snuff. These differences are disappearing rapidly, reflecting the incorporation of women with smoking in the previous years.
Another part of this type of cancer is caused by inhaled substances and who are in the workplace, a phenomenon related to the 10% -15% of lung cancer in males and 5% in women. The most important of these substances are asbestos, such as those used in asbestos factories.
Lung cancer can also be caused by radiation received at the chest, such as treatment with radiation therapy used to treat breast cancer and lymphoma. The interval between radiation exposure and cancer onset is usually very long, around age 20. The greatest risk are people who tried for many years with old appliances, and smoked during the following years. The risk with modern radiotherapy equipment is very low.
Hereditary factors have little relation to lung cancer.
