Hispanics have lower cancer screening rates; are diagnosed with cancer at later stages
By Rebecca Siegel, MPH
A new Cancer Facts & Figures for Hispanics/Latinos has been released in conjunction with National Hispanic Heritage Month. This publication is updated every 3 years and is a resource for current information about cancer among Hispanics. But you may be wondering why we produce a 35-page report devoted solely to cancer statistics for Hispanics.
For 60 years the American Cancer Society's Research department has promoted cancer prevention and control by providing cancer data in a user-friendly format called Cancer Facts & Figures. Over the years, new Facts & Figures publications have been developed to highlight a particular cancer type or a specific population. In 2000, to answer the increasing demand for more in-depth information on cancer in the growing Hispanic community, the inaugural Cancer Facts & Figures for Hispanics/Latinos was introduced.
Hispanics Fastest-Growing Minority in US
Promoting cancer prevention and control in the Hispanic community is more important than ever because Hispanics are the largest and fastest growing minority population in the United States. As we learned from the 2010 census conducted by the U.S. Census Bureau, more than 16% of Americans, 50.5 million people, identify themselves as Hispanic. The 43% increase in the Hispanic population over the past decade -- compared to a 10% increase in the total population -- accounted for more than half of the overall population growth. By 2050, approximately 30% of all Americans will be Hispanic, which means that more and more new cancer patients will be Hispanic. More...

I've seen a few articles recently about removing the fallopian tubes to prevent ovarian cancer, a procedure called "prophylactic bilateral salpingectomy". And not just in women who are at high risk for ovarian cancer, which is already recommended by gynecological medical societies in the United States, but for all women who are not planning to have any more children and who are about to undergo abdominal surgery for any reason.
I can see the appeal given that many, if not most, ovarian cancers actually originate in the fallopian tubes. In fact, it is more common to find microscopic fallopian tube cancer than microscopic ovarian cancer in women with a BRCA1 or BRCA2 mutation when they have their ovaries and fallopian tubes removed. (These mutations put them at higher risk for ovarian and breast cancer.) And unfortunately we don't yet have an accurate test to screen women for ovarian cancer, so these cancers are usually found at a late stage when they are often fatal.
It is common for women to get their "tubes tied" (i.e. tubal ligation) as a form of permanent birth control, and we know this reduces the risk of ovarian cancer. But removing the fallopian tubes is a more invasive procedure, and the potential benefits and potential harms are largely unknown. Is it worth it? Does it really reduce the risk of ovarian cancer and, if so, by how much? More...

During 2011, the Food and Drug Administration (FDA) approved 30 completely new therapies (new molecular entities, as opposed to the modification of an old drug), 7 of which were for treatment of different types of cancer. One of them, the lung cancer drug crizotinib, was decades in the making. For a new drug, that isn't necessarily a lot of time.
Why does it take so long to get cancer treatments to the patients who need them? The answer lies both in the complexity of cancer and the complexity of the drug development and testing process. More...

Before writing a blog about soy and breast cancer, I took an informal poll of a few friends to get a sense of what women believe about soy. I asked them, "What do you know about eating soy food? Is it good for you? Not good for you?" (I didn't even mention breast cancer.) The responses I got were, "I think it acts like estrogen in the body"; "Consuming any soy products increases the risk of breast cancer"; "I don't eat it a lot because I heard something negative but I can't remember what it was;" and "I've heard you should only have it in moderation." Apparently, people are hearing that soy may not be good. But what's the truth? In this blog I'll walk you through what we know and what we don't know about soy and breast cancer, and give you some practical tips on eating soy. More...

These days we hear a lot about health disparities, cancer disparities, health equity, etc. What is this all about? And why do these terms seem to be more discussed now?
MedlinePlus, the National Institutes of Health's website for patients, describes health disparities as "differences between groups of people. These differences can affect how frequently a disease affects a group, how many people get sick, or how often the disease causes death."
For the World Health Organization (WHO), health equity is "the absence of unfair and avoidable or remediable differences in health among population groups defined socially, economically, demographically or geographically."
Essentially, health equity is about everyone getting a fair shake when it comes to health and healthcare. More...

When I talk with people who have gained weight during their cancer treatment, they are often shocked. For people who lost considerable weight before their diagnosis and then felt better once their treatment started, weight gain can be a welcome change. But more often I speak with people who were at a healthy weight or overweight before treatment and did not realize that their treatment might cause some weight gain. More...

Vaccines are not new. In fact, there is evidence that the ancient Egyptians and Chinese used them many centuries ago. Vaccines work by preparing your own immune system to attack invading pathogens, thus preventing disease. Vaccines have helped us make great inroads against many deadly diseases over the past 60 years, when they became used more widely.
Using vaccines against cancer is relatively new, though. Cancer researchers have been trying to make vaccines for tumors, just like others have made vaccines for measles, mumps, and tetanus. More...

June is turning out to be big month for cancer survivors. Not only did we celebrate National Cancer Survivor Day on the 7th, but the Society is also co-hosting the 6th Biennial Cancer Survivorship Research Conference June 14 -16 in Arlington, VA.
And the American Cancer Society has just released the first-ever Cancer Treatment and Survivorship Facts & Figures, the newest addition to our Facts & Figures publications. The report highlights the continued increase in numbers of cancer survivors in the United States. Survivors are defined as any person with cancer from the time of diagnosis on.
We estimate that there are now 13.7 million Americans alive today who have a history of cancer, and that this number is expected to grow to nearly 18 million by 2022. More...

Most people's impression of pathology is based on the forensic pathologists in TV shows such as "CSI" (or, if you're my age, "Quincy, ME"). But for people facing cancer, there is another aspect of pathology to learn about - the testing that is done to find out whether an area of diseased tissue is benign (not cancer) or malignant (cancer).
Doctors often suspect that a person has cancer based on their physical exam findings and on the results of x-rays and scans. In the vast majority of cases, however, samples of cells (called cytology) or tissue samples (biopsies) must be tested to know for sure. And, if the tumor is cancerous, pathology testing will also determine what kind of cancer is present. This information is very important in guiding the treatment you receive, and in estimating your outlook for recovery and survival.
People receiving treatments for cancer usually get to know the teams of professionals who perform surgery and who prescribe and give their chemotherapy and radiation. On the other hand, you rarely meet the pathologists, technologists, and other laboratory professionals who test the biopsies, blood, and other specimens removed from your body. Learning about what they do with your samples can help you make informed decisions about your care. More...

Hookah smoking is no safer than cigarette smoking. If you read no further, that is the take-home message for this blog -- no matter what you may have heard or read, the scientific evidence is clear that hookah smoking is not a safe alternative to smoking cigarettes.
Countering the widely-held, although mistaken, belief that hookah smoking is safer than cigarette smoking is important, so let's take a step back and consider what hookah is, learn about its history and current popularity, and then look at the facts about the scientific evidence regarding its effects on health.
