Coffee linked with Cancer

coffee

A new study finds people who drink more than 4 cups of caffeinated coffee a day have half the risk of dying from oral/pharyngeal cancer as people who drink it either occasionally or not at all. However, the researchers say their findings need to be confirmed by more research, and for now should just be received as good news for coffee drinkers and not be used as a reason to recommend everyone should drink 4 cups of coffee a day.

Oral/Pharyngeal Cancer

Oral/pharyngeal or mouth and throat cancer is rarely diagnosed in the early stages because symptoms usually do not appear until the cancer is advanced. Also, the symptoms can be mistaken for something else, such as toothache.

The cancer can sometimes be spotted early during a routine exam by a doctor, dentist, or dental hygienist, and some dentists and doctors suggest you look at your mouth in a mirror at least once a month to check for symptoms.

The most common symptoms are a mouth sore that fails to heal, or a pain in the mouth that doesn’t go away.

The biggest risks for developing oral/pharyngeal cancer are tobacco and alcohol use. Most people who have it are tobacco users.

Researchers Examine Link with Coffee

Previous epidemiological studies have suggested coffee drinking is linked to a reduced risk for mouth and throat cancer.

It has also been suggested that it may not be the caffeine in coffee, but the fact it is rich in antioxidants, polyphenols, and other compounds, that help prevent or slow the development of cancer.

The study gathered a wealth of lifestyle and health information on 968,432 men and women, including their tea and coffee consumption. When they enrolled on the study, none of the participants had cancer, but over the 26 years of follow up, 868 died from oral/pharyngeal cancer.

When they analyzed the tea and coffee consumption in relation to deaths from oral/pharyngeal cancer, the researchers found those participants who reported drinking more than 4 cups of caffeinated coffee a day had a 49% lower risk of death from oral/pharyngeal cancer compared to those who reported not drinking coffee at all or only an occasional cup.

Conclusion and Next Step

The researchers conclude:

“In this large prospective study, caffeinated coffee intake was inversely associated with oral/pharyngeal cancer mortality. Research is needed to elucidate biologic mechanisms whereby coffee might help to protect against these often fatal cancers.”

“We are not recommending people all drink 4 cups of coffee a day. This is just a little bit of good news for those of us who enjoy coffee.”

“There may be some other effects of coffee that may prevent people with certain conditions from drinking a lot of caffeine,” she cautions, noting that:

“This study is about just one cancer site among many. There needs to be much more consistent research before we can support the conclusion that coffee should be consumed for cancer prevention.”

The team is now planning to analyze links between coffee consumption and cancer in a more diverse population.

The Society hopes to recruit at least 300,000 adults from a range of ethnic and racial backgrounds across the US to take part in CPS-3, which aims to increase knowledge of how to prevent cancer.

There has been a lot of debate recently about the benefits and harms of coffee drinking, with more recent news suggesting the benefits probably outweigh the harms.

But researchers spreading the good news are all saying the same thing, as Hildebrand and colleagues themselves point out in this latest study: while there appear to be some health benefits to drinking coffee, there also are a few concerns, and the evidence is not solid enough to actively encourage people to go out and drink coffee.

Prostate Cancer and Diet

Prostate Cancer and The Diet

So, recently one of my Dad’s best friends (which means he’s referred to as an Uncle), was diagnosed with stage 2 Prostate Cancer. So, naturally this was pretty hard news to handle, especially being so close to this family friend. I started looking into more information on the specific cancer and these are some things that I found…

Prostate cancer is a malignant tumor in the prostate, the male gland that produces fluid that makes up part of the semen. The prostate gland is about the size of a walnut. It is attached to the bottom of the bladder and surrounds the urethra. The growth and function of the prostate are controlled by male hormones, like testosterone. Prostate cancer is often slow-growing, and is sometimes present for years before symptoms appear. The five-year survival rate for patients with early diagnosis and treatment is close to 100%.

Prostate Cancer is the most common cancer among men in the United States after skin cancer. More than 200,000 new cases occur annually. It is the second leading cause of cancer deaths in men, after lung cancer. Roughly, 27,000 deaths are attributed to prostate cancer each year.

The cause of Prostate Cancer varies. A man’s age, ethnicity, and family history are all risk factors that cannot be changed. Research is underway to clarify how risk linked to hormone levels, including testosterone and insulin-like growth factor (IGF), may be changeable. Current research suggests that you can reduce your chances of developing prostate cancer by making healthy dietary choices.

Making diet and lifestyle changes can reduce your risk of cancer. Research shows that eating a mostly plant-based diet, maintaining a healthy weight, and getting regular physical activity lowers risk of prostate and other cancers.

Experts suggest that some food choices may be linked to prostate cancer. Foods that probably offer protection against prostate cancer include:

  • Foods containing lycopene, an antioxidant. Lycopene is most commonly found in tomatoes and tomato products, and fruits like red or pink grapefruit, watermelon, and guava.
    • Lycopene supplements don’t necessarily provide the same health protection benefits as lycopene from food.
    • Foods containing selenium. This mineral is plentiful in Brazil nuts, seafood, meat, and poultry.

Foods that are a probable cause of prostate cancer are:

  • Foods high in calcium. However, as the evidence of cancer risk and diets containing cow’s milk, cheese, and other foods high in calcium seems to be in conflict with findings on other types of cancer, there is no recommendation to change how much you consume.
