Q. Hi Fitz, I'm a woman in my early 40s and have really let myself go over the past decade. I used to have a nice figure, but now I'm stuck with a 'lumpy bumpy butt' that is far too big. The rest of my body needs work too. I joined Weight Watchers two weeks ago, cause I saw that you wrote it was a great program. I'm down three pounds already. So, what do you advise I do to improve my backside. It's awful! Marlene

A. Hello Miss Marlene. I'm glad you sent me your question, and I'm confident I can help. There are a lot of things you can do to tighten up that tush. You've already taken the first step with Weight Watchers -- losing weight will be most important for getting rid of bulging pockets of fat.

What is it about us guys that makes us so bent on fixing, shifting, adjusting, and grabbing our crotches? A question for the ages, perhaps. Maybe it's because we're subconsciously aware of the need to be checking for signs of testicular cancer (by the way, guys -- feel free to use that excuse the next time you get caught with your pants down).

All joking aside, testicular cancer is the most common form of cancer in males ages 15 to 34, making a monthly testicular self-examination extremely important. Unlike some other forms of cancer, testicular cancer can be somewhat asymptomatic, save for the growth of a lump on the testicle or the slight enlargement of the testes. This, again, is what makes the regular self-examination of the utmost importance.

Early detection of testicular cancer is vital to ensuring that all treatment options can be made available. For more detailed information on self-examinations, as well as the disease itself, visit the National Institutes of Health's website by clicking here.

Although great strides have been taken in recent years in spreading awareness and information about breast cancer, it seems there is a lot of confusion about what the symptoms are. Besides the well-known "lump," do you know what else to look for? And do you know what symptoms don't usually mean breast cancer? Apparently 25% of women wrongly believe a persistent cough is a sign of breast cancer.

Good news! Researchers are reporting that there may be a less painful, and more accurate, way to scan breast tissue for abnormalities. Called the "Cone Beam Breast Computed Tomography" scanner, this new form of x-ray is basically a fancier version of the CT scan. It takes a three-dimensional view of the breast and the surrounding tissue, even over into the armpit, all without compressing anything between cold glass plates.

So far the scanner has detected all cancers found by standard mammography, and in one case created a clearer image of a cancer that was hard to see on the mammogram. Researchers are hopeful so far, saying that although several trials are still needed before the study is complete, it looks as though the new scan can detect more tumors than the mammogram can.

If approved, this procedure would be much pricier than a mammogram, and therefore most likely reserved for those at highest risk. But regardless, I'm sure women all over the world will have their fingers crossed that the results so far hold true!
