Might be enough: The requirement for number of tube comes from both the type of tube needed for a particular test as well as the volume of blood needed. The volume part also depends on how concentrated your blood is--less liquid in your blood means you need more tubes. Your doctor will be notified if some of the tests needed could not be done, and then he or she can decide if you need to be drawn again.

No problem: In all likelihood, this should not be an issue. Tumor markers are generally not recommended for patients with a history of breast cancer, primarily because the markers that we have are quite poor. They tend to be most helpful when tumors are advanced and when patients are undergoing chemotherapy. If the tumor markers go down, this is often taken as a sign that the therapy may be working.

Ask your doc: You should ask your treating physician if the extra tubes are necessary. If they are return to the lab once you are fully hydrated.

A 21-year-old member asked:

I'm a man, should I get human papilloma virus vaccine to avoid genital warts and cancer?

Yes: The vaccine has been approved by the fda for ages 9-26 in men. The biggest advantage of the vaccine is to reduce the spread of the virus to women, which can be aided by reducing the number of men with the virus. Male genital cancer is much rarer than female cervical cancer, so the major benefit is preventing some types of warts an spread to women.

Why can arm swelling and pain happen after breast cancer surgery?

Dr. Barry Rosen

Lymphedema: An essential part of breast cancer staging is the removal of some of the lymph nodes under the armpit. The lymphatic system's job includes draining tissue fluid and bringing it back into the circulation. Lymph node removal short-circuits this process leading to the risk of chronic swelling, or lymphedema. The less nodes removed, the lower the risk.

In select patients, even a positive sentinel node may not mandate completion axillary node dissection. Also, with modern chemotherapy, even patients with gross positive node disease up front may be converted to node negative status with neoadjuvant therapy and spared axillary node dissection given a negative sentinel node following neoadjuvant therapy.

Take with food: Do not take the medicine on an empty stomach and it sometimes is helpful to take medicines such as antacids that are used to treat gastritis. Many people can take Plavix (clopidogrel) without problems. Some of the medications can interfere with the action of the Plavix (clopidogrel) so consult your physician.

My body keep on giving odd reaction, it trembles up from my chest through the throat until the jaws, so to the hands. Could it be hyperthyroidism?

...: Could mean fatigue, are you sleeping 6h-8h every night? Do you wake up at the same time most days? Do you drink 3qts/water daily? Do you walk 30 minutes every day? If not, your body is tired and wants to sleep, so will have to be shaken, or shivered, to wake up. If you walk 30min daily, avoid fried & sugary food, drink 3qts water daily, you see the difference.
