I thought a thread which listed the SECOND most common cause of things would be interesting, as all of us can easily find the most common cause, but second most common is harder to come by.

Heres one to start:

Prostate cancer is the second most common cause of cancer in men, right after skin cancer.
 
Squamous cell carcinoma is the second most common tumor arising on sun-exposed sites in older people, exceeded only by basal cell carcinoma.
 
Coronaviridae 2nd MCC common cold

Rhinoviruses "~50% of common colds" in child & adult
(Rhinovv = 30-50% viral causes of common cold, Coronaviruses=10-15%)

staph saprophyticus is the 2nd most common cause of uti's in young women (to e.coli)

klebsiella is the 2nd most common cause of CAP in alcoholics (to s. pneumo)

these 2nds are good ones bc people are often fooled into thinking they're #1
 
Fetal alcohol syndrome is the most common preventable cause of mental ******ation. Not sure about second-most or about the most common cause of mental ******ation...
FAS is the most common preventable. Fragile X is the most common hereditary. Down's is the most common congenital cause overall. I am pretty sure CP is the most common cause overall.
