It seems today most people obtaining tattoos are more concerned about the quality of the tattoo and the effect of aging altering the tattoo, than any potential long term health risks. The health dangers associated with being injected by hundreds of needles into the dermis or the inner layer of the skin are widely publicised and most tattoo artists take these issues very seriously. We have all heard about Aids and Hep C, but are you aware of the current debate on the possible skin cancer risks associated with tattoo inks?
Recent years have seen an increase in stories associated with the potential of getting skin cancer from tattoo inks. Limited studies taken to date have not confirmed a direct link between cancer and tattoo inks..
Phthalates and other chemical ingredients used in tattoo inks have raised questions about the long term risks on our health such as skin cancer.It has been reported that some forms of phthalates are believed to have the potential to disrupt testosterone or mimic estrogen. Phthalate exposure has been identified to possible sperm defects and altered thyroid hormones. The phthalates in tattoo inks are believed to be cleared from the body within hours unlike many other forms of phthalate exposure. A study reported that Phthalates applied to the skin in a lotion were absorbed and metabolised and the same thing is likely to happen with the phthalates in tattoo inks. It would be well advised for pregnant and nursing women to avoid any exposure to phthalates.
Injecting tattoo inks, containing exogenous pigments, into the dermis creates a unique situation, due to the large amount of metallic salts and organic dyes remain in the skin for a lifetime. The potential carcinogenic risks of tattoo inks remain debatable. Several studies have identified the presence of potential carcinogenic or procarcinogenic products in tattoo inks.One chemical commonly used in black tattoo ink called benzo(a)pyrene is known to be a potent carcinogen that causes skin cancer in animal tests. As tattooing injects inks such asbenzo(a)pyrene directly into the dermis damaging the skin. You could conclude it may contribute to skin cancer.
Scientists and health professionals continue to debate the possible link between tattoo inks and cancer. In the last forty years there have only been 50 documented cases of squamous cell carcinoma, malignant skin melanoma or basal cell carcinoma with possible connections to tattoos, compared to the millions of tattoos obtained. Epidemiological studies on the effects of tattoo ink could be taken, although they would not be easy. A large number of tattooed people would have to be monitored over a long period of time to see whether they developed problems such as skin cancer near their tattoos. The low number of reported skin cancers arising in tattoos could be considered coincidental.
Colorectal cancer or bowel cancer is a type of cancer that forms from uncontrolled cell growth. This growth originates in portions of the large intestine; although it also may form in the appendix. Perhaps unsurprisingly, bowel cancer forms from the cells lining the organ.
This form of cancer mainly affects the large bowel, while the small bowels remain relatively cancer-free. The condition is the second most common cause of cancer-related deaths. At least six percent of people in Western countries end up developing the condition. Bowel cancer is curable in 40 to 50 percent of most cases, generally with the help of surgical intervention.
How does the condition form?
The cells in the colon may undergo a series of ‘mutations,’ controlling how the cells there divide and survive. When the cells start dividing in an uncontrollable manner, the result may produce a clump of malignant or cancerous cells. Polyps or an adenoma, clumps of abnormal cells resting on the end of a normal cell stalk, form after these mutations take place.
During this phase, the adenoma is considered pre-cancerous; just five percent of these malignant polyps become cancerous, sometimes life-threatening in nature. This happens when the polyp starts swelling over a long period of time. The abnormal cells start infiltrating the polyp, later spreading to the underlying colon tissue where the polyp resides. At this point, the cancer starts appearing in affected patients.
What are the symptoms?
Bowel cancer’s many symptoms start once the cancer infiltrates a patient’s colon tissue. Constipation is a common symptom, once the cancerous growth starts to block a portion of the lower bowels. If the bowel becomes completely obstructed, a patient generally starts experiencing severe abdominal pain and vomiting.
Cancerous growths in the proximal colon’s lumen portion are likely to cause symptoms of innate tiredness, shortness of breath and bouts of nausea. Bleeding from the rectum is also a common symptom, which may lead to the loss of blood over time.
