Ten Most Common Cancers in Men and Women

 Ten Most Common Cancers in Men and Women  

Cancers caused about 25% of deaths in Britain in 1991 and is one of the leading cause of mortality  and morbidity worldwide. Its estimated that 14 million cases and 8.2 million deaths occurred in 2012. The number of new cases is expected to rise by 70% in the next two decade. Breast cancer is the most common cancer in women and lung cancer in men. Cancer is not a single disease; more than 200 types of cancer are known. Cancer are result of uncontrolled cell division. The type of nuclear division involved is mitosis. The problem is caused by mutations or abnormal activation of the genes which control cell division. When the genes are abnormal they are called oncogene (onkos means tumor). About 100 of these have been discovered. 

                                                               

 A single faulty cell may divide to form a clone of indentical cells. Eventually an irregular mass of relatively undifferentiated cells called a tumor is formed. Tumor cells can break away and spread to other parts of the body, particularly in the bloodstream or lymphatic system, causing secondary tumors or metastases. This process is called metastasis. Tumors that spread and eventually cause ill health and death are described as malignant. The majority of tumors, such as common warts, do not spread and are described as benign.

   There were an estimated 14.1 million cancer cases around the world in 2012, of these 7.4 million cases were in men and 6.7 million in women. This number is expected to increase to 24 million by 2035.
