Artery-opening procedures sometimes used inappropriately

Having a clear coronary artery is better than having a blocked coronary artery, it’s safe to say. And procedures such as angioplasty as a means of increasing blood flow are considerably less invasive than the old-fashioned surgical alternative. But doctors may be turning to even these less-invasive options a bit too readily, a new review suggests.

Carmageddon is coming, so chill out and crank up the tunes

Are you ready for Carmageddon, the lockdown of a 10-mile stretch of the 405 Freeway in Los Angeles July 16 and 17? The lucky people who don't have to hit the roads will probably stay put, but undoubtedly some will get stuck -- as in trapped like a caged animal -- in horrible traffic.

Late-speaking toddlers do catch up behavior-wise, study finds

Parents often worry if their toddlers are slow to start speaking in sentences, but a new study has found that otherwise normal 2-year-olds late to learn words aren’t more likely than their peers to have behavioral or emotional problems in their childhood and teenage years.

Celebrex might prevent lung cancer in former smokers, early studies suggest

The Cox-2 inhibitor celecoxib, better known under the brand name Celebrex, might be able to prevent lung cancer in former smokers, researchers said Wednesday. Studies in a small group of people suggest that the drug, which is normally used to treat arthritis and some other inflammatory diseases, prevents a proliferation of cells that is normally a precursor of lung cancer, the researchers reported in the journal Cancer Prevention Research. But a great deal more research will be necessary to show that the drug actually prevents the initiation of cancer and then that it prevents deaths, experts said.

Salt reduction: Heart benefits unclear in new study

Cutting back on salt does seem to reduce blood pressure -- welcome news for those diligently watching their intake -- but it might not reduce deaths, a new analysis suggests. 

Anti-HIV drug Kaletra can cause adrenal problems in newborns

Using the anti-AIDS drug Kaletra prophylactically in newborn infants of HIV-positive women may cause potentially life-threatening adrenal problems in some of the infants, French researchers reported Tuesday. Although no deaths have been reported from such use, the routine prophylactic use of the drug should probably be discontinued, particularly because other effective drugs are also available, the team reported in the Journal of the American Medical Assn.

Massage--including the kind you get at the spa--may improve lower back pain

Massage therapy may hit the spot for people suffering from low back pain. A recent study in the journal Annals of Internal Medicine found that two types of massage--relaxation and structural--improved function and pain for people with low back pain, compared with regular treatment.

Men juggle too: Competing work and family demands stress out more guys nowadays

A growing number of men are now suffering from the seductive promise that they can have it all: the comforts and rewards of a fulfilling family life, a job that brings satisfaction and a paycheck big enough to support the needs of the aforementioned family, and freedom from conflict between the demands of each.

Autism may be environmental, but it can also run in the family

Autism is an environmental illness -- at least in some cases. Just as lead paint chips can cause learning disabilities and radon in the basement can cause lung cancer, certain chemicals and other outside influences seem to help set autism in motion.

Cancer risks: Breast density score is a number from 1 to 4

Breast density would be included in a mammography report under a bill proposed in the California Senate. What that would mean for women is receiving a score of 1 to 4 to help her and her doctor better assess her individual risk of developing breast cancer.

Women should know their breast density, study says; how many do?

Mammograms should be recommended to women based on several individual risk factors, such as age, family history and breast density, doctors said in a study published Monday in the Annals of Internal Medicine.

Judging penis size by comparing index, ring fingers

Penis length cannot be determined by how big his hands or feet are -- those and other supposed indicators have been widely discredited for years. But now a team of Korean researchers has produced what may be a more reliable guide: the ratio of the length of his index finger to that of his ring finger. The lower that ratio, the longer the penis may be, the researchers wrote Monday in the Asian Journal of Andrology.

Talk Back: CT scans, mammograms, Avastin, Provenge: Who pays?

Widespread screening with CT scans can detect lung cancer. Regular mammograms of all women 40 and older can find breast cancer. Avastin, at $8,000 a month, has helped some patients with advanced breast cancer.  And the prostate cancer drug Provenge, at $93,000 per patient, can extend survival by about four months.

Hugo Chavez, the pelvic abscess and the mystery cancer -- how long will it take to get back to Venezuela?

Venezuelan President Hugo Chavez has acknowledged that he's fighting cancer, but he won't say what kind. Chavez, who looked as if he'd lost some weight, spoke from Cuba, where he's been at a medical facility for three weeks. Officials have said that Chavez had emergency surgery June 10 for a pelvic abscess, a collection of pus -- kind of like a dangerous internal pimple -- that's generally situated in the lower abdomen.

Diet soda and weight gain: The connection may be, in a way, what you think

Diet soda may indeed be associated with weight gain, as a new study suggests, but the fault may lie in your head, not necessarily your metabolism.
