My father had pulmonary tuberculosis nearly 4 decades ago. Clinically, it had been considered healed tuberculosis after timely treatment along with years of monitoring. Even until 2 years ago before diagnosis of lung cancer, the only thing showing on his chest X-ray was a localized calcification (i.e., calcium deposition, a mark of healed lesion in his case) without any visible changes. Also, he was symptomless concerning any upper-respiratory diseases. Unexpectedly, there were some lung malignancies clearly showing on his very last chest X-ray in 2009 — one that appeared significantly different compared with the one taken 2 years prior.
There are countless similar stories regarding the link between personal histories of infectious diseases and cancer. A friend of mine died of liver cancer in his 40s — a real tragedy given his age. It turned out that he had hepatitis (infected with hepatitis B virus) when he was young.
It’s scientifically proven with regards to infection-associated cancer. Pancreatic inflammation appears to increase the risk of pancreatic cancer, and some patients with pancreatic cancer had history of pancreatitis. A history of urinary tract infection is currently accepted as a risk factor for developing bladder cancer, and has been positively linked to the development of renal cell carcinoma (kidney cancer), with notably elevated risks for men with a history of smoking.
An infective agent is linked to some of the most common cancers. Human papilloma virus (HPV, also called “wart virus”) is responsible for cervical cancer, one of the most common cancers affecting women. A two-fold danger exists with this disease. First, HPV is highly transmissible and considered the most common sexually transmitted infection in most populations; second, most women infected with the virus may become negative within 2 years, or HPV infection can persist for years in the body without causing any problems. However, women with persistent high-risk HPV infections are at the greatest risk for developing cervical cancer. A recent study showed that a sexually transmitted bacterial infection (known as trichomoniasis) has been linked to increased risk for advanced prostate cancer – the illness that strikes nearly 200,000 American men each year.

This doesn’t mean that you’ll develop cancer if you have any infection or inflammation, because infection alone usually does not lead to cancer. However, it does mean that you need to control your infection, get it treated timely, and thereafter be vigilant about any cancer risk factors and live a healthy lifestyle.

If you’ve followed the news about the oil spill in the Gulf Coast for the past month and half, if you’ve seen the tragic images of oil-soaked or oil-coated animals, or learned of the climbing toll of dead and injured birds and marine animals, you’re probably concerned about how much threat this oil disaster poses to our health. Although a few experts claim its toxicity is minor to humans, such advice does little to ease public worries and fears.
The sun emits three types of invisible ultraviolet (UV) rays, i.e. UVA, UVB, and UVC. It damages the human skin primarily through UVA and UVB. UVA rays are responsible for rashes, and allergic reactions, while UVB rays, for sunburns. Surely, both UVA and UVB speed up skin aging; yet more seriously, they cause skin cancer. These effects vary with seasons, time of the day and location on the planet related to the sun. For instance, the rays are strongest between 11 a.m. and 3 p.m. in the summer. Threat of UVC rays is negligible, since they are essentially blocked by the ozone layer.
Skin cancer can occur just about anywhere on the skin, but most often on the areas exposed to the sun — the scalp, neck, face, lips, ears, arms, hands, and legs. It can also appear in odd places, such as between your toes, underneath your nails, and even around your genitals. With that in mind, here are some characteristics on what to look out for, particularly regarding moles, bumps or skin spots:
Size: Any new or growing blemish bigger than 5 mm (or a pencil eraser).
Color: A combination of more than one color.
S stands for Sunscreen application. Use a moisturizer with SPF 15 or higher on a daily basis. Sun Protection Factor 15 provides protection 15 times longer before sunburn. Accordingly, SPF 30 provides protection 30 times longer. Make sure to use sunscreens that block both UVA and UVB.
H stands for Hiding from the sun. Skin is the largest organ in the body; it’s essential to preserve its function. Whether you stroll under the sun or enjoy outdoors adventures, wear sunglasses, a hat, and cover up with loose clothing. Also, make sure your sunglasses have both UVA and UVB blocking properties.
E stands for Educate everyone. Remember, E is for education, not entertainment under the sun! Start with children and young adults. Instruct skin care equally to women and men. Regardless of gender and age, we are all exposed to the same sun. These days, the sun is even more unkind compared to two or three decades ago due to changes in ozone protection. Thinning ozone layers in the atmosphere cannot filter out UVA radiation and UVB radiation as well as they could previously. 
Therefore, skin damage happens earlier and at a deeper level.
Stress and its negative effects may have accumulated over the winter months, fueled by darkness, extreme cold and snow, limited outdoor activity, work, deadlines, and worries over holiday debt. It’s really getting to you, right? Well, it’s time to get rid of it. With spring coming, an increase in natural sunlight, greening trees and blooming flowers can all improve your mood. So, embrace spring beauty!
Do you have a variety of canned foods stocked in your pantry and/or refrigerator? 
Certain plastic containers and bottles have been linked to cancer risk. Several scientific studies have demonstrated that a biologically active chemical BPA (Bisphenol A) is released from polycarbonate bottles into the bottle content after simulated normal use. BPA can be released when the plastic item is washed, heated, and/or re-used. This impacts adults as well as children.
