    The latest study on HPV and lung cancer:
    Correlation between squamous cell carcinoma of the lung and human papillomavirus infection and the relationship to expression of p53 and p16. X Fan, K Yu, J Wu, J Shao, L Zhu, J Zhang. Tumour Biol. 2014 Dec 28 [Epub ahead of print]. 128 adenocarcinomas and 134 squamous cell carcinomas in Shanghai. “The rate of HPV infection in SQC cases was significantly higher than in ADC cases (12.69 versus 3.91 %). Females with SQC had a significantly higher rate of HPV infection compared to males with SQC (18.75 versus 7.14 %, p?=?0.044). HPV infection was correlated with gender and age in SQC but not with the degree of tumor differentiation, TNM stage, or smoking.”

    And don’t turn up your nose just because it’s not 100% of lung cancer caused by HPV. Remember the supposed smoking-related mechanism the anti-smokers peddle (benzo(a)pyrene diol epoxide-DNA adducts at hot spot codons at p53 in lung cells) could only pertain to about 7% or less of lung cancers.

    7 % or less would explain why so few smokers get LC to start with! LC is a very rare disease even in smokers where 2% or less of life long smokers ever get LC..

    How oxygen in the air could trigger lung cancer: Rates of the disease found to decrease at higher altitudes.
    US researchers suggest way our bodies process oxygen is potentially carcinogenic.
    Free radicals in body can cause damage to cell structures and DNA, which in turn can trigger cancer.
    Link between elevation and lung cancer not seen with breast, prostate or bowel cancer.

    Rates are per 100,000 persons. Rates are per 100,000 persons.

    Note the age where LC is found…………..OLD AGE group incidence hits the 500/100,000 at age 75-85

    AGE it seems is the deciding factor……….
