Breast cancer




Breast cancer is an uncontrolled growth of breast cells. To better understand breast cancer, it helps to understand how any cancer can develop.

Cancer occurs as a result of mutations, or abnormal changes, in the genes responsible for regulating the growth of cells and keeping them healthy. The genes are in each cell’s nucleus, which acts as the “control room” of each cell. Normally, the cells in our bodies replace themselves through an orderly process of cell growth: healthy new cells take over as old ones die out. But over time, mutations can “turn on” certain genes and “turn off” others in a cell. That changed cell gains the ability to keep dividing without control or order, producing more cells just like it and forming a tumor.

A tumor can be benign (not dangerous to health) or malignant (has the potential to be dangerous). Benign tumors are not considered cancerous: their cells are close to normal in appearance, they grow slowly, and they do not invade nearby tissues or spread to other parts of the body. Malignant tumors are cancerous. Left unchecked, malignant cells eventually can spread beyond the original tumor to other parts of the body.


The term “breast cancer” refers to a malignant tumor that has developed from cells in the breast. Usually breast cancer either begins in the cells of the lobules, which are the milk-producing glands, or the ducts, the passages that drain milk from the lobules to the nipple. Less commonly, breast cancer can begin in the stromal tissues, which include the fatty and fibrous connective tissues of the breast.

Over time, cancer cells can invade nearby healthy breast tissue and make their way into the underarm lymph nodes, small organs that filter out foreign substances in the body. If cancer cells get into the lymph nodes, they then have a pathway into other parts of the body. The breast cancer’s stage refers to how far the cancer cells have spread beyond the original tumor .

Breast cancer is always caused by a genetic abnormality (a “mistake” in the genetic material). However, only 5-10% of cancers are due to an abnormality inherited from your mother or father. About 90% of breast cancers are due to genetic abnormalities that happen as a result of the aging process and the “wear and tear” of life in general.

While there are steps every person can take to help the body stay as healthy as possible (such as eating a balanced diet, not smoking, limiting alcohol, and exercising regularly), breast cancer is never anyone's fault. Feeling guilty, or telling yourself that breast cancer happened because of something you or anyone else did, is not productive.


Breast Cancer Facts and Figures




Breast cancer is the most commonly diagnosed cancer in women
The risk of breast cancer increases with age and if you live to 90 years your risk of developing this cancer is almost 14%
1.7 million breast cancers were diagnosed worldwide in 2007
465,000 (approx.) women died due to breast cancer in 2007
North America, Australia, Europe have the highest incidence of breast cancer
Large parts of Africa and Asia have the lowest rates
In the last 25 years it incidence has gone up by 30% in the western world
Increased risk of developing breast cancer include -
Start of menstrual period at an early age
Menopause later in life
Having a first or second degree relative with breast cancer
Obesity
Consumption of alcohol
Never having children
Using contraceptives
Using hormone replacement therapy during post-menopausal years
Certain inherited genetic mutations for breast cancer (BRCA1 and/or BRCA2)
Decreased Breast cancer Risk -
Breast feeding
Moderate Physical activity
Maintaining normal weight
Stop smoking
Breast cancer can be prevented by screening
Early treatment can increase chances of 5 years survival to 98%
Women with a BRCA mutation who get their ovaries surgically removed can reduce their risk of breast cancer by over 50%.
A study from North Carolina State University indicated that Women who performed the act of fellatio and swallow semen regularly (one to two times a week) may reduce their risk of breast cancer by up to 40 percent!!

Thyroid - Hypothyroid - Meaning - Causes - Symptoms - Treatment

What is Hypothyroid? Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. Causes About three percent of the general population is hypothyroidic. Factors such as iodine deficiency or exposure to Iodine can increase that risk. There are a number of causes for hypothyroidism. Iodine deficiency is the most common cause of hypothyroidism worldwide. In iodine-replete individuals hypothyroidism is generally caused by Hashimoto's thyroiditis, or otherwise as a result of either an absent thyroid gland or a deficiency in stimulating hormones from the hypothalamus or pituitary.

Common diseases linked to vitamin D deficiency

Sunlight is that the body's main supplier of Vitamin D that is critical for sturdy bones and teeth. Vitamin D is in virtually each tissue, therefore, it's vital for the health of the entire body. However, five hundredths of individuals over fifty have low levels of Vitamin D. Studies have shown that an absence of it will result in polygenic disorder, depression, cardiopathy, hip fractures, cramp, and disseminated multiple sclerosis. If we do not get enough Vitamin D our cells will multiply too quick and grow to become malignant tumors increasing a risk of breast, colon, prostate, ovary, gullet and humor cancers. Lack of Vitamin D may also interfere with endocrine secretion therefore it might have an effect on polygenic disorder sufferers it absolutely was found in 'Archives of General Psychiatry' that deficiencies result in depression as a result of it affect the small endocrine glands behind the thyroid and that they become hyperactive...

Back pain - Meaning- causes - Exercises

The lower spine consists of five bones, called the lumbar vertebrae. The vertebrae support the body and protect the spinal core and nerves. Between each vertebra is a disk filled with a jelly-like material. The disks act as shock absorbers for the vertebrae. Along the spine are many nerves. Injury to these nerves can cause pain. What can cause low back injuries? Many things can cause low back injuries - muscle strain or spasm, sprains of ligaments (which attach bone to bone), joint problems or a "slipped disk." The most common cause of low back pain is using your back muscles in activities you're not used to, like lifting heavy furniture, playing basketball or doing yard work. A slipped disk happens when the disk between the bones bulges and presses on nerves. This is often caused by twisting while lifting. But many people won't know what caused their slipped disk. Back pain can also follow normal activities such as bending over the sink to brush your teeth. Back pain...
