As you’ve probably heard, a well-respected group of World Health Organization scientists said glyphosate, the active ingredient in Monsanto’s wildly popular Roundup herbicide and its generic cousins, is probably capable of causing cancer in humans.

Here are five things you should know:

1. What the report said: Roundup could cause cancer in humans.

When children are diagnosed with acute lymphoblastic leukemia now, they have more than a 90 percent chance of survival.

But when James Eversull was told he had leukemia in 1964, there wasn't much hope.

He was just 18 months old when his parents discovered what was wrong.

Marcie Sillman talks to Dr. Joann Elmore, University of Washington professor of medicine, about the findings of her new study that suggest the results of breast cancer biopsy tests might not be accurate.

Marcie Sillman talks with University of Washington professor Dr. Mary-Claire King about her groundbreaking research that changed the way we treat breast cancer today. 

When a doctor tells a patient that she has cancer and has just a year left to live, that patient often hears very little afterward. It's as though the physician said "cancer" and then "blah, blah, blah."

Anxiety makes it difficult to remember details and the worse the prognosis, the less the patient tends to remember. Recent studies have found that cancer patients retain less than half of what their doctors tell them.

When Barbara Marder was diagnosed with lung cancer three years ago, she had part of her right lung removed, went through a round of chemotherapy and tried to move on with her life.

"I had hoped that everything was fine — that I would not create difficulty for my children, that I would get to see my grandchildren grow up," says Marder, 73, of Arnold, Md.

But a routine scan a year later found bad news: The cancer was back — this time in her other lung.

Owain Weinert, at age 8, hadn’t been eating breakfast and was sleeping 12 to 14 hours a night. For months, mysterious fevers came and went.

His mother took him to the pediatrician, who in turn sent them to a lab for a blood test. They then went to lunch, which Owain didn’t eat.

China Warns Of Cancer Epidemic

Nov 19, 2014

Cancer rates may be falling in many Western countries, but they are rising steadily in China. The country’s top health officials have issued a strong warning about the spread of cancer.

All types of the disease are, it seems, becoming increasingly common. Blame the effects of pollution and unhealthy habits.

The BBC’s Celia Hatton traveled to the coastal city of Tianjin to see how Asia’s largest cancer treatment center is handling the onslaught.

Since Richard Nixon declared war on cancer in 1971, the National Cancer Institute has poured some $90 billion into research and treatments. Yet a cure remains elusive.

After removing a tumor, surgeons are confronted with an unfortunate reality: They can’t be sure they got it all. It can be difficult to distinguish between normal tissue and cancerous cells while operating.

Dr. Jim Olson, a researcher at Fred Hutchinson Research Center and oncologist at the University of Washington, was inspired by his young patients to find a way to ensure that surgeons didn’t miss anything.
