I was hoping you could answer a question for me about birth control pills. There is a history of breast cancer in my family (my mother). Is it true that because of this, it is unsafe for me to use birth control pills? A few friends have recently had condoms break during sex, and I am looking for a type of "backup" contraception system.

Do men need to cover up their testicles when using indoor tanning facilities?

I use tanning booths regularly and I normally use only eye protection. I am slightly worried, however, that the UV radiation from the sunlamps could do internal damage to a man's testicles, because the skin is obviously only very thin and might not offer much protection against UV radiation. Since eyelids are similarly thin and it is known that eye damage can result even when using tanning equipment with closed eyes, I wonder if advice should be given to men to use similar precautions to prevent testicles being exposed to high-intensity UV-A or UV-B radiation. I have looked everywhere for scientific information on this matter but could not find anything. Your advice on this matter would therefore be very much appreciated.

I have been a Type II diabetic for several years. I am now told I am beginning to show kidney insufficiency — is there a diet, or can you tell me where to find diet information of foods that a diabetic can use that are lower in protein and/or a renal diet?

I have recurring insomnia which lasts for about eight to twelve days. It seems to begin at about the same time each month. What are the common causes of sleep disturbance? Any suggestions?

I relocated to a new area within the past six months. Since then, I have been experiencing congestion in the morning and pressure in my sinus area, such as stuffed nose and difficulty breathing, at night when I lay on my back and in the morning. Although I do not have a cold, I seem to always have a small amount of drainage on a daily basis. Within the past week, I am sneezing quite a bit in the mornings and at night, my eyes are so itchy I can't help but rub them to a nice shade of red. I have never had allergies before, just for your info. Thanks for any tips.

1) I'm considering getting my tongue pierced. Is there anything I ought to know before I get it done? What should I look for in a piercing place? Does the piercing ever have negative effects — I don't know, tongue paralysis or something? Thanks!

2) If and when I decide to take my tongue ring out, I worry that there will be scarring tissue or an ugly hole in the middle of my tongue. Is this the case?

I have had Crohn's disease for 16 years and am in remission right now. Recently my boyfriend and I have been toying with the idea of anal sex, but I'm concerned about it given my health issues. I have a lot of thickening of the terminal ileum walls and worry that the "trauma" of anal sex could set off a flare up and be painful because of the narrowing. Any thoughts? I'm way too embarrassed to discuss this with my male doctor. Thanks!

My boyfriend doesn't "pre-cum." Could there be something wrong? Or is it common? All the other guys I have been with have not had this problem.

I read that disposable contact lenses are actually worse for your eyes than the normal one-year ones because they allow less oxygen to go to your eyes, and the only advantage is that there are less cleansing problems. Also, it is claimed that inadequate oxygen to your eyes (possibly caused by prolonged wearing of contact lenses) leads to a condition when extra blood vessels sprout around the iris, which leads to sight problems at old age. Is that true?

I am very concerned because I normally wear (one-year) contact lenses from 8am to 8pm, and maybe to 12am during reading periods. I don't feel very comfortable with glasses because they give distorted visions and fatigue. I thought switching to disposable contact lenses would do my eyes good. My current lenses contain 38 percent water. Is this good enough?
