and  | { Thats the reason | post-menopausal | estrogen } | is\n\
given together with another hormone called\n\
progestin: The combination lowers the risk of\n\
endometrial cancer.\n\
\n\
But the NTP advisers said putting all\n\
estrogens on the federal list would help\n\
women trying to balance the benefits and\n\
risks when choosing hormone therapy.\n\
Physicians never discuss any of these risks\n\
when they are prescribing hormone therapy.\n\
They only discuss benefits. Listing might\n\
force it on the table, Michelle Medinsky, a\n\
toxicologist from Durham, N.C., said before\n\
the vote.\n\
\n\
The committee of scientists advises the NTP,\n\
a branch of the National Institutes of Health\n\
that every two years updates the federal list\n\
of proven and suspected cancer-causing\n\
substances.\n\
\n\
The NTP typically follows its advisers\n\
recommendations, but an officially updated\n\
carcinogen list isnt expected until 2002.\n\

Thursday, after a daylong debate, the panel\n\
declined to add talc powder to the list,\n\
saying there wasnt enough evidence linking\n\
its use in feminine hygiene products to\n\
ovarian cancer. The panel deadlocked over\n\
whether to a second type of talc, fibrous\n\
talc that some studies have linked to lung\n\
cancer in talc miners.\n\
\n\
On Wednesday, the panel voted to add\n\
ultraviolet radiation -- those\n\
sunburn-causing rays long known to cause skin\n\
cancer -- to the official carcinogen list.\n\
\n\
The panel on Friday continued debating an\n\
association between cancers of the nose and\n\
sinuses with industrial exposure to wood\n\
dust.\n\
\n\
Talc has long been controversial. When\n\
studies first appeared suggesting it migrated\n\
into the ovaries to cause tumors, many\n\
feminine hygiene products replaced talc with\n\
cornstarch.\n\
\n\
Panelist Medinsky said she had been prepared\n\
to list talc powder as reasonably believed\n\
to cause cancer. But after listening to\n\
hours of industry attacks on the science,\n\
the evidence has knocked me out of the\n\
reasonably category into not list, she\n\
said before the panel voted 7-3 against\n\
listing talc.\n\

Talc in one form or the other can be found in\n\
many papers, paints, ceramics, food wrappers,\n\
hard candy, chewing gum, cosmetics and pills.\n\
Most people are familiar with talc as a loose\n\
powder used in cosmetics and as a drying\n\
powder.\n\
