Written by Doc Team Friday, 28 May 2010 08:26
Breast cancer is the most common lethal neoplasm in women. The American Cancer Society (ACS) has estimated that breast cancer will constitute 29% of all new malignant neoplasms and 16% of deaths from cancer in women. The annual incidence of breast cancer in the United States increases dramatically with age (5 per 100,000 population at 25 years of age, rising to 150 per 100,000 at 50 years of age and to more than 200 per 100,000 at 75 years of age).
The incidence of male breast cancer is about 2.5 per 100,000 population. Fewer than 1% of all breast cancer cases occur in men.Breast cancer is the result of mutations in one or more critical genes. Two genes in women on chromosome 17 have been implicated. The most important gene is called BRCA-1 (at 17q21); the other is the p53 gene (at 17p13). A third gene is the BRCA-2 gene on chromosome 13.

Infection of the kidney with Mycobacterium tuberculosis tends to produce chronic destructive lesions in the kidney. Characteristically there is marked distortion of the architecture of the pelvicaliceal system and an irregular configuration of the kidney. It is believed to be due to hematogenous spread of the organism during primary infection with reactivation of the disease many years later.
In the male, there is often concomitant infection of the bladder, prostate, epididymis and testicle. The first clinical manifestation of renal tuberculosis may be a nontender scrotal mass or obstruction at the ureteropelvic junction producing hydronephrosis. Tuberculosis often produces localized areas of ureteral inflammation and obstruction due to granuloma formation.

Disorders and diseases of the skeletal system range all the way from flatfoot to deadly bone cancer. They may be broadly categorized as osteodystrophies, inflammatory lesions and tumors. Osteodystrophies are a group conditions in which there is an abnormality of development, form, or structure of bone. Inflammatory lesions include bone infections (osteomyelitis) and arthritis (rheumotoid arthritis). Tumors of bone are uncommon. Some cancers start in bone, whereas others are the result of metastasis.
Curvature of The Spine
One out of every 10 young people age 10 to 14 will develop some curvature of the spine. An abnormal curvature of the spine with rearward convexity is called kyphosis ; an abnormal forward curvature of the spine in the lumbar region is called lordosis ; a side to side curvature is called scoliosis. In most cases the cause is unknown, and the condition cannot be prevented.
