Facts and Treatment of Childhood Cancer

Childhood CancerNew cases: An estimated 10,400 new cases are expected to occur among children aged 0-14 years in 2007. Childhood cancers are rare.

Deaths: An estimated 1,545 deaths are expected to occur among children aged 0-14 years in 2007, about one-third of these from leukemia. Although uncommon, cancer is the second leading cause of death in children, exceeded only by accidents. Mortality rates for childhood cancer have declined by 48% since 1975.

Early detection: Early symptoms are usually non-specific. Parents should make sure their children have regular medical checkups and should be alert to any unusual symptoms [Read more...]

Breast Cancer Treatment and Early Detection

Early detection: Mammography can detect breast cancer at an early stage when treatment may be more effective. Numerous studies have shown that early detection saves lives and increases treatment options. The recent declines in breast cancer mortality among women have been attributed to a combination of early detection and improvements in treatment.

Mammog-raphy is highly accurate but like most medical tests, it is not perfect. On average, mammography will detect about 80%-90% of breast cancers in women without symptoms. All suspicious lumps should be biopsied for a definitive diagnosis. Several recent studies have shown that magnetic resonance imaging appears to be more sensitive than mammography in detecting tumors in women with an inherited susceptibility to breast cancer [Read more...]

Breast Cancer – Facts About Breast Cancer

Breast CancerTopic: Explaining About Breast Cancer – Facts About Breast CancerNew cases: An estimated 178,480 new cases of invasive breast cancer are expected to occur among women in the US during 2007. Breast cancer is the most frequently diagnosed cancer in women. After continuously increas-ing for more than two decades, female breast cancer incidence rates leveled off from 2001-2003. About 2,030 new cases of breast cancer are expected in men in 2007.

In addition to invasive breast cancer, 62,030 new cases of in situ breast cancer are expected to occur among women in 2007. Of these, approximately 85% will be ductal carcinoma in situ (DCIS) [Read more...]

How Is Cancer Staged?

Cancer StagingHow Is Cancer Staged? Staging describes the extent or spread of the disease at the time of diagnosis. It is essential in determining the choice of therapy and in assessing prognosis. A cancer’s stage is based on the primary tumor’s size and location and whether it has spread to other areas of the body. A number of different staging systems are used to classify tumors.

The TNM staging system assesses tumors in three ways: extent of the primary tumor (T), absence or presence of regional lymph node involvement (N), and absence or presence of distant metastases (M). Once the T, N, and M are determined, [Read more...]

How Many People Alive Today Have Ever Had Cancer? The National Cancer Institute estimates that approxi-mately 10.5 million Americans with a history of cancer were alive in January 2003. Some of these individuals were cancer-free, while others still had evidence of cancer and may have been undergoing treatment.

How Many New Cases Are Expected to Occur This Year? About 1,444,920 new cancer cases are expected to be diagnosed in 2007. This estimate does not include carcinoma in situ (noninvasive cancer) of any site except urinary bladder, and does not include basal and squamous cell skin cancers. More than 1 million cases of basal and squamous cell skin cancers are expected to be diagnosed this year [Read more...]

What Is Cancer? Facts About Cancer

Breast CancerWhat Is Cancer? Cancer is a group of diseases characterized by uncon-trolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death. Cancer is caused by both external factors (tobacco, chemicals, radiation, and infectious organisms) and internal factors (inherited mutations, hormones, immune conditions, and muta-tions that occur from metabolism).

These causal factors may act together or in sequence to initiate or promote car-cinogenesis. Ten or more years often pass between expo-sure to external factors and detectable cancer. Cancer is treated with surgery, radiation, chemotherapy, hormone therapy, biological therapy, and targeted therapy [Read more...]
