Vaping Linked to Bladder Cancer

A study has linked smoking e-cigarettes to higher risk of bladder cancer.

Dr. Sam Chang of Vanderbilt-Ingram Cancer Center in Nashville, reported in an American Urological News release, “We’ve known traditional smoking raises bladder cancer risk, and given the surge in popularity of e-cigarettes, it’s imperative we uncover any potential links.”

Chemicals in cigarettes and electronic cigarettes, such as nicotine, are excreted through the urine. Researchers examined the urine of e-cig users vs. those of non-smokers and found 92% of those who vaped had at least two of the five chemicals tested.

The University of Minnesota in 2015 identified chemicals commonly found in e-cig vapor to include:

 

Formaldehyde (human carcinogen)

Acetaldehyde (carcinogen related to alcohol drinking)

Acrolein (highly irritating and toxic)

Toluene (toxic) NNN, NNK (tobacco carcinogens related to nicotine)

Metals (possible carcinogens and toxicants)

In a second study, researchers looked at bladder tissue to see what nicotine and some of the chemicals in vapor could do.  They found nicotine, nitrosamines and formaldehyde not only damaged lining but blocked the DNA repair, hence increasing risk of bladder cancer.

Although exact causes of bladder cancer are unknown, tobacco smoke has been the single greatest risk factor.  Other risk factors for bladder cancer include diets rich in fried foods, arsenic, radon, occupational exposure to aromatic amines in textile, rubber and paint plants, and some medications such as pioglitazone used in diabetes.  Being exposed to a worm causing schistosomiasis can also put one at risk for bladder cancer.

Symptoms of bladder cancer include blood in the urine (hematuria), difficulty urination due to obstruction, pain/burning with urination (dysuria), and sometimes no symptoms at all.

Bladder cancer is treated by surgery, radiation, chemotherapy or immunotherapy.  The earlier its diagnosed, the easier it is to treat.

According to the American Cancer Society they project for 2017:

  • About 79,030 new cases of bladder cancer (about 60,490 in men and 18,540 in women)
  • About 16,870 deaths from bladder cancer (about 12,240 in men and 4,630 in women)

How many of these being related to electronic cigarettes is unknown.
