Comment

Increased risk to develop lung cancer has been observed in patients with asthma[1] but the opposite has been reported as well[2]. Moderate excess colorectal cancer and bladder cancer (males) has been found as well[1]. A recent meta-analysis found no confincing evidence for an increased risk of cancers of the breast or colorectum in patients with asthma, hay fever or any allergy[3].
(discussing the genetics of asthma is beyond the scope of FaCD)
