There are many simple day to day things that can help keep your immune system strong. These include maintaining a balanced diet, getting enough sleep and minimizing the amount of stress your body experiences. In addition to these daily routines you can also take a natural immune support supplement such as larch arabinogalactan.
1 AnswerThe development of lymphedema can be detected using a testing method called bioimpedance spectroscopy, which measures extracellular fluid in the limbs by passing low-dose electric current through the limb, to detect the way the body responds to fluid changes. The test is painless, fast (five minutes), noninvasive and portable.

Dendritic cells are found in the blood. They are essential for the start of any immune response, be it against a bacterial infection, a viral infection or tumor cells. Moreover, these dendritic cells are also responsible for telling the body what type of immune response to initiate, so that the invader can be attacked with the most effective tools.

Anyone who has had an axillary lymph node dissection as part of breast cancer surgery is at increased risk for upper extremity lymphedema (swelling due to a blockage of the lymph passages). Sentinel node biopsies also carry a risk of lymphedema, but to a much lesser extent. Lymphedema can occur immediately postoperatively or within a few months, a couple of years, or as late as 20 years after treatment. With proper education and care, the incidence of lymphedema can be minimized or, if it develops, kept well under control.
2 AnswersRealAge answeredYour immune system is responsible for helping fight off everything from the common cold to cancer -- a tall order!
Send in some reinforcements so it doesn't get battle fatigue. Here are four foods your immune system loves.
Oranges, yogurt, tea and pumpkin seeds are the order of the day when it comes to giving your immune system a treat, according to Michael Roizen, MD, and Mehmet Oz, MD, authors of the best-selling (and now newly expanded and updated) YOU: The Owner's Manual. Here's how these four superfoods help:
- Oranges are chock-full of vitamin C, an antioxidant vitamin that helps your immune system fend off disease-causing invaders. Other good C options are bell peppers, strawberries, cantaloupe and broccoli. Or take 400 milligrams of vitamin C three times daily.
- Yogurt (unpasteurized) contains Lactobacillus acidophilus -- a healthy bacterium that helps thwart fungus-related infections. Or take a 20-milligram acidophilus supplement twice daily.
- Tea is full of flavonoids, powerful vitamin-like substances that reduce immune-system aging. You'll also find them in oats, onions, broccoli, tomatoes, apples and berries.
- Pumpkin seeds are great year-round, not just at Halloween, because they contain zinc -- a nutrient that's been shown to help reduce the average length of the common cold.

The stealth virus is the name one researcher has given a virus that he believes resides in the body without detection by the immune system. He reports that the stealth virus has been obtained from tissues of patients with chronic fatigue syndrome and other chronic conditions and believes that this virus could be the cause. However, the existence of the virus has not been confirmed by other investigators. Also, the same researcher found similar rates of viral detection in both sick subjects (chronic fatigue syndrome) and healthy subjects. If a stealth virus were a cause of these illnesses, one would expect more infection among the ill than the healthy.
The researcher says to be suspicious of the polio vaccine because the source of the stealth virus is the African green monkey, and kidney cells from the African green monkey are used in the production of live oral polio vaccine. To date, the researcher's results have not been confirmed in independent laboratories. The Centers for Disease Control and Prevention (CDC) found no evidence that polio vaccine, or any other vaccine, has been contaminated with a stealth virus.
2 AnswersJoel Fuhrman, MD, Family Medicine, answeredDendritic cells are tree-shaped immune cells that are scattered throughout the body in their immature or deactivated form. When activated they trap and process what they recognize as enemy material to present it to other immune cells to remove or kill the threat. That is, they capture microbial pathogens and abnormal cells so the other immune cells can destroy them.
Dendritic cells are present in tissues in contact with the external environment, such as the skin and the inner lining of the nose, lungs, stomach, and intestines. They can also be found in an immature state in the blood. Once activated, and engaged they migrate to the lymph nodes where they interact with T cells and B cells to initiate an immune attack. Dendritic cell functions can decrease with aging leading to loss of immune function. This gradual loss in dendritic function exposes us to infection and a higher risk of developing cancer as we get older.
General: Complications of lymphedema include skin infections, extreme swelling (elephantiasis), and cancer of the lymph vessels. Many of the complications may be prevented by vigilant skin care and hygiene.
Depression: It may not be possible or comfortable to perform normal tasks using the affected arm or leg. This may lead to frustration and depression.
Elephantiasis: Elephantiasis occurs when the affected arm or leg becomes so hardened with thickened skin that is difficult to move it. The skin on the affected arm or leg may be affected by persistent ulcers and repeated infections.
