Let.s Start Screening For Breast Health

Let's Start Screening For Breast Health
 by: Brenda Witt
In the United States, American women are told to begin annual mammographic screening for breast cancer at the age of 40. Long before we've reached this age, we are advised to perform a monthly breast exam and see our doctors for a clinical breast exam (CBE) annually as well. However, the detection rate of breast cancer for CBE is only 47% when the tumors are less than 1 centimeter while mammography has given us a 70% detection rate. By the time a tumor is detected by palpation or found mammographically, it has already been growing and developing for 8-10 years.
Mammography has a high false positive rate. Only 1:6 biopsies are found to be positive for cancer when performed due to a positive mammogram or CBE. This places additional stressors on women who undergo these procedures.
Other risks of mammography include the radiation that each breast is exposed to during a mammogram. During a chest X-ray, a person receives 1/1000 of a RAD, or radiation absorbed dose. This type of X-ray is a high energy X-ray. During a mammogram, however, the X-ray used is a low energy X-ray and results in 1 RAD or a 1000-fold greater exposure than a simple chest X-ray. It has been suggested that the low energy X-ray used may cause greater biological damage which is cumulative over time. In a journal entitled Radiation Research and published in 2004, the author concludes that the risks associated with mammography screening may be FIVE times higher than previously assumed and the risk-benefit relationship of mammography exposures need to be re-examined.
In 1982, the FDA approved thermography as an adjunctive tool for breast cancer screening. Digital Infrared Thermal Imaging, also known as DITI measures heat emitted from the body and is accurate to 1/100th of a degree. Certified Clinical Thermographers follow strict guidelines and transmit their scans for interpretation by board certified thermologists. DITI examines physiology, NOT structure. It is in this capacity that DITI can monitor breast HEALTH over time and alert a patient or physician to a developing problem; possibly before a lump can be seen on X-ray or palpated clinically. There are no test limitations such as breast density. Women with cosmetic implants are great candidates for thermography which emits no radiation and no compression. Contact is never made during a thermographic scan.
Clinical research studies continue to support thermography's role as an adjunctive tool in breast cancer screening and the ONLY tool that measures breast health. There are now more than 800 publications on over 300,000 women in clinical trials. A recent finding published in the American Journal of Radiology in 2003 showed that thermography has 99% sensitivity in identifying breast cancer with single examinations and limited views. Scientists concluded that a negative thermogram is powerful evidence that cancer is not present.
In conclusion, women need to begin breast health screening early; as young as age 25. This can provide women with the earliest possible indication that further investigation is necessary. It takes approximately 15 years for a breast cancer to form and lead to death. If "early detection is the best prevention," let's start using technology that truly allows for the earliest possible alert to a developing problem.
Thermographic screening is not covered by most insurance companies but is surprisingly affordable for most people. For more information or to find a certified clinic in your area, go to www.proactivehealthonline.com.

Vitamins For Vegetarians

Vitamins For Vegetarians
 by: Simon Harris
There are a lot of vegetarians amongst us, some by circumstance and some by choice. Those that are vegetarians by choice can be divided into two general groups, those that do not eat meat, poultry or fish, but do consume dairy products as – in theory – the animals are not harmed or killed by the gathering of those products. Vegans, however, use no animal products whatsoever.
There are many health benefits to a planned vegetarian diet, as opposed to the unplanned vegetarian diets that result from poverty and a lack of food availability. However, there are also some special precautions that need to be taken to safeguard nutrition, as adequate amounts of some of the most important nutrients can be more difficult to obtain. This is especially true for those following the more restrictive vegan diet.
The body is a complex and delicate system, and the foundation of all of its functioning is chemical and electrical actions, interactions and reactions. The operation of this system rests firmly upon the balance of these chemicals. The majority of the chemicals in these essential physical processes come from the food that we eat, from the nutrients that come from its consumption. Thus, nutrition has a deep influence of the health of the body and the quality of its functioning.
Because the brain, like the body, functions on chemical reactions and electrical impulses, the processes of cognition, emotion, and so on, are also affected by nutrition. In fact, deficiencies in certain vitamins and minerals can result in mental illness and retardation, as well as cognitive dysfunction and difficulties and emotional instability.
The Vitamin B complex offers a perfect example of how vegetarians must pay special attention to their diets to ensure peak performance of body and mind. The Vitamin B complex is involved with every major system in the body and has a role in almost every important bodily process. It is essential to mental health and functioning, and essential to life itself. However, there are certain Vitamin B complex vitamins that need special attention by vegetarians, as vegetarians do not consume the richest sources of these vitamins.
The richest sources of Vitamin B2 are milk and organ meats. It is available in enriched breads and cereals, but care must be taken to consume the right amount daily. Niacin and Vitamin B6 are other B complex vitamins in which the richest sources are meats and, again, are available in smaller concentrations in enriched breads and cereals. Vitamin B12 is only found in animal products. It is important to note that vitamin B12, in addition to being important to the production of red blood cells, is essential for the normal growth of children.
Nutritional supplements can serve to enhance the health benefits of the vegetarian lifestyle. Indeed, they can serve to prevent the serious health consequences that vitamin deficiency can cause. Nutrition is especially essential for children, as their minds and bodies are growing and developing. If you are vegetarian or vegan, you may want to consider the complete, safe and reliable nutrition that dietary supplements can provide.

Exercise Can Reduce Risks Of Diabetes

Exercise Can Reduce Risks Of Diabetes
 by: Simon Harris
The 2 types of diabetes are type I and type II. Type I diabetes is characterized by the pancreas making too little or no insulin. An individual with diabetes type I will have to inject insulin throughout the day in order to control glucose levels. Type II diabetes, also known as adult onset diabetes, is characterized by the pancreas not producing enough insulin to control glucose levels or the cells not responding to insulin. When a cell does not respond to insulin, it is known as insulin resistance. When a subject is diagnosed with type II diabetes, exercise and weight control are prescribed as measures to help with insulin resistance. If this does not control glucose levels, then medication is prescribed. The risk factors for type II diabetes include: inactivity, high cholesterol, obesity, and hypertension. Inactivity alone is a very strong risk factor that has been proven to lead to diabetes type II. Exercise will have a positive effect on diabetes type II while improving insulin sensitivity while type I cannot be controlled be an exercise program. Over 90% of individuals with diabetes have type II.
Exercise causes the body to process glucose faster, which lowers blood sugar. The more intense the exercise, the faster the body will utilize glucose. Therefore it is important to understand the differences in training with type I and type II diabetes. It is important for an individual who has diabetes to check with a physician before beginning an exercise program. When training with a diabetic, it is important to understand the dangers of injecting insulin immediately prior to exercise. An individual with type I diabetes injecting their normal amount of insulin for a sedentary situation can pose the risk of hypoglycemia or insulin shock during exercise. General exercise guidelines for type I are as follows: allow adequate rest during exercise sessions to prevent high blood pressure, use low impact exercises and avoid heavy weight lifting, and always have a supply of carbohydrates nearby. If blood sugar levels get too low, the individual may feel shaky, disoriented, hungry, anxious, become irritable or experience trembling. Consuming a carbohydrate snack or beverage will alleviate these symptoms in a matter of minutes.
Before engaging in exercise, it is important for blood sugar levels to be tested to make sure that they are not below 80 to 100 mg/dl range and not above 250 mg/dl. Glucose levels should also be tested before, during, after and three to five hours after exercise. During this recovery period (3-5 hours after exercise), it is important for diabetics to consume ample carbohydrates in order to prevent hypoglycemia.
Exercise will greatly benefit an individual with type II diabetes because of its positive effects on insulin sensitivity. Proper exercise and nutrition are the best forms of prevention for type II diabetics. It is important for training protocols to be repeated almost daily to help with sustaining insulin sensitivity. To prevent hypoglycemia, progressively work up to strenuous activity.
As with individuals with type I diabetes, carbohydrates should also be present during training to assist in raising blood sugar levels if the individual becomes low.
