Breast Cancer

Abstract

There are several types of cancers in United States of America but, over last thirty years, breast cancer has been diagnosed as one of the common cancers among women. It is not only common in United States but, other parts of the world. At the end of 2007, it has researched that, 17480 women were diagnosed with breast cancer and, 40,460 women might die of breast cancer. From several years, breast cancers had increased the mortality rate in United States, especially North America and North Europe. It is less common in Southern Europe and Latin America. Studies have showed that, immigrants to North America and Northern Europe proved that, environmental factors contributed a lot in raising breast cancers. Today, lots of research is going to investigate that, environmental chemicals also play important role in the development of breast cancer and, also well known carcinogens which may include metals, play vital role in the initiation and promotion of breast cancer.

Introduction

Breast cancer is the common cancer in women, and, according to the estimate, the rate of this disease is one third to the total population of the female. This cancer is causing much mortality worldwide between the ages of 40 and 55. It has been found that, out of 8 females, one female develops breast cancer in United States. The death rate due to breast cancer has been controlled within previous decade but, it had increased in the past over fifty years. It has been found that, 25% to 30% women, die of breast cancers and, remaining women about 70% to 75% die of other diseases. The diagnosis of breast cancer is not essentially the sentence of death, which is the thought of several females (Chung et, al, 2008). It has been researched that, mortality rate is greater in young females less than age 35 and, very old age, above than 75. The young females have aggressive disease and, very old may not be treated aggressively and, chances of recurrences occur in the first 3 years and, chances of recurrence is found up to 20 years.

Pathology of Breast Cancer

It has been researched that, ninety five percent of breast cancers are found to be carcinomas that is meant, they develop from breast epithelial elements. Doctors have divided breast cancer into two types, such as in situ carcinomas and invasive carcinomas. The in situ carcinomas may develop in ductal or lobular epithelium, and remained there for long time.

Risk Factors for Development of Breast Cancer

Breast Cancer is also common in North America and Northern Europe and, uncommon in Asia and Africa. Several studies have shown that, migration factors do not influence to a large extent to the incidence of the disease and, environmental and life style factors contribute much as risk factors for this disease.

Gender is also considered the risk factor to a large extent ...
