Really, according to this article from Business Week which reports on tax authorities in Brazil classifying cosmetic surgery as a tax deductable expense :

Adriana Pires, a human resources manager in Rio de Janeiro, had a pleasant surprise when she prepared her income taxes: the 8,000 reais ($4,575) she paid for breast implants and liposuction are tax-deductible.As Brazilians race to meet today’s filing deadline, the federal government this year for the first time will allow taxpayers to deduct the cost of boob jobs, tummy tucks and any other type of cosmetic surgery. The measure, retroactive to procedures performed since 2004, may spur the 3 billion reais plastic surgery market, the world’s second-largest after the U.S., according to Brazil’s Plastic Surgery Society.
