A cancer-stricken woman on TLC's "My Strange Addiction" swears by the healing properties of her own urine -- drinking it, rubbing it on her skin, even BATHING in it -- and the footage is stomach-turning.

53-year-old Carrie has been drinking her own urine for 4 years -- downing about 80 ounces of the yellow stuff a day -- and despite a total absence of medical proof, she believes it's helped control her cancer. Carrie says in the show finale (which airs Sunday at 10 PM) ... she  hasn't seen a doctor in 6 years.

Carrie doesn't just drink her pee -- she brushes her teeth with it, uses it as lotion, pours it in her hair, bathes in it ... even rinses out her eyeballs with it.

Although Carrie insists her obsession is life-saving -- she says she's noticed a strange mole on her back that changes daily from dark to light.

Here's some non-pee advice -- go to a doctor.
