Second cancers are on the rise. Nearly 1 in 5 new cases in the U.S. now involves someone who has had the disease before.

When doctors talk about second cancers, they mean a different tissue type or a different site, not a recurrence or spread of the original tumor.

Thousands of protesters poured into Beirut's Riad al-Solh Square on Sunday demanding that the country's top politicians resign, hours after Prime Minister Tammam Salam hinted he might step down following violent protests triggered by a monthlong trash crisis.

The demonstrations, the largest in years, railed against the corruption and dysfunction that has brought about Lebanon's current political crisis. The country does not have a functioning cabinet or parliament, and hasn't had a president for more than a year.

An international human rights watchdog has decried police violence against Lebanese demonstrators protesting the government's failure to resolve the country's mounting trash crisis.

Police used forced to disperse a protest of around 100 people in downtown Beirut this week after some of the demonstrators tried to break a security cordon around the government building.

Dr. Dre has issued a statement to the New York Times apologizing to "the women I've hurt" without specifically acknowledging the reason for the apology.

Mexico is objecting to a U.S. decision to negatively certify it for not doing enough to reduce the deaths of endangered sea turtles in fishing nets.

Even though Linda Ellerbee has addressed many tough topics with young audiences before, it took a decade before Nickelodeon approved her idea of a "Nick News" episode where children with terminal illnesses talk about their lives.

Her show, "Before I Go ... Living With Dying," airs on the children's network Sunday. The four featured children who are incurably ill address losing friends, fears for themselves and others, and their changed outlook on life.

For the first time, there's evidence that a diabetes medication, Jardiance, reduces risk of the complications that are the top killer of diabetics: heart attacks, strokes and other cardiovascular damage.

Preventing those is a long-elusive goal for the millions of diabetes patients and their doctors, and one analyst who's also a trained physician even called Thursday's news of a possible groundbreaking advance a "holy grail."

New research shows that chances of dying from very early breast cancer are small but the disease is riskier for young women and blacks, the same disparities seen for more advanced cancer.

Death rates in the 20 years after diagnosis totaled about 3 percent for women whose breast cancer was confined to a milk duct. The death rates were twice as high for those younger than 35 at diagnosis and in blacks — but still lower than those with more common invasive breast cancer.

Progressive Socialist Party chief Walid Jumblat denounced the “barbaric” behavior that the security forces used in confronting Wednesday's protests of the You Stink campaign, assuring that the demonstrations are “righteous.”
