Back in - let me see - round about - goodness, could have been 30 years
ago - The Lancet published an item saying that on examining cancers from
some women (forget whether ovaries or uterus) they had found sharp
particles of talc in the very centre of them. They reasoned that this
was probably from when the women were babies and were showered with lots
of baby talc.
Looking for the reference to the article via Google I see:

TALC AND CARCINOMA OF THE OVARY AND CERVIX
An extraction-replication technique was used to examine tissue from
patients with ovarian and cervical tumours. In both conditions talc
particles were found deeply embedded within the tumour tissue. The close
association of talc to the asbestos group of minerals is of interest.

Perineal use of talc and risk of ovarian cancer
s its physical form and does not imply the presence of asbestos. The
purer forms (approximately 90% mineral talc) are used for cosmetic and
hygiene products including baby powders and feminine hygiene products.
Perineal use of cosmetic talc is a common practice in the United
Kingdom, North America, Australia and some other countries. To our
knowledge accurate estimates of prevalence of use of cosmetic talc are
not available. However, the use for female hygiene of body powders, baby
powders, talcum powders and deodorising powder, most of which contain
cosmetic talc in varying amounts, has been reported to be as high as 50%
in some countries.3
From pathological studies it is known that particles and fibres that
enter the body can migrate to distant organs. For instance, asbestos
fibres have been found in ovaries from women exposed to asbestos.4 5
Analogously, following perineal application, talc particles can migrate
from the vagina to the peritoneal cavity and ovaries.6 A majority of
women experience retrograde menstruation7; this suggests a mechanism by
which talc particles can travel through the female reproductive tract to
the ovaries. Furthermore, epidemiological studies have shown decreased
risks of ovarian cancer after tubal ligation and/or hysterectomy,
suggesting that removing a pathway by which carcinogenic substances can
reach the ovaries reduces the risk.
The association between talc use in the perineal region and ovarian
cancer was investigated in one cohort study, case-control studies.In the
cohort study, arguably the strongest study because of its partly
prospective ascertainment of exposure, there was no .......
Information on talc use in infancy is generally insufficient in the
case-control studies. However, in one study the exposure to baby powder
was reported by 42.2% of the cases and 40.5% of the controls. In several
of the other studies patients were asked about age at first use of
perineal talc, as an indicator for use in infancy or other periods of life.
Only four case-control studiesand one cohort study10 provided results by
histological type. In four of these studies, in particular the cohort
study, there were hints of higher risks of serous tumours related to
talc exposure.
Before 1976, talc was to some extent contaminated with asbestos, so that
the early studies relating talc to ovarian cancer may have been
confounded by the asbestos. However, the association between talc
exposure and ovarian cancer is as strong in recent studies, as in
earlier ones, diminishing the likelihood that all these results are
influenced by contamination of talc by asbestos.
... women who used talc experienced excess risks of ovarian cancer; some
results were statistically significant and some were not. There was some
indication in the cohort study of an increase in serous tumours. The
evidence of talc migrating to the ovaries lends credibility to such a
possible association. . ... All leading to their conclusion that ....
evidence is insufficient to establish a causal association between
perineal use of talc and ovarian cancer risk

The following queries were raised in the link and a DHS reply basically
said there was no real problem.

A while back a friend of mine brought to my attention an item which you
published on the possible link between condoms and cancer in women
(WDDTY, vol 6 no 2). If this is true it must be the greatest medical
scandal of all time. ....Talc is used in the manufacture of latex goods
both as a lubricant and to release the product from the mould used in
its manufacture. The use of talc on surgical gloves was virtually
eliminated early in the 1990s since there was evidence that it created
inflammation and adhesions in some surgical patients (Arch Dermatol,
1994; 130: 48-53). Although some condom manufacturers still use talc as
a dry lubricant, others use dry lubricants such as silicone and
cornstarch. ... The harmful effects of talc on human tissue were first
recorded in the 1930s. Thirty years later there was a reported case of a
woman who had a significant amount of talc in her peritoneal (abdominal)
cavity talc which matched that found on the surface of her husband's
condoms (Lancet, 1963; 1: 1295-6). The authors concluded that talc
travelled up through the fallopian tubes and became implanted in the
peritoneal cavity. They also predicted that talc might contribute to
occlusion (blockage) and sterility. A more ominous series of studies
linked talc to ovarian cancer talc was observed in a number of ovarian
and uterine tumours as well as in ovarian tissue (Lancet, 1979; 2:
349-51; J Ob Gyn Br Commonwealth, 1971; 78: 266-72) and it has since
been confirmed that talc, either placed on the perineum (or on the
surface of underwear, sanitary towels, diaphragms or condoms), can reach
the ovaries via ascent through the fallopian tubes (Am J Epidem, 1989;
130-394; Ob Gyn, July 1992). There has been little attention paid to the
possibility of damage to the male urogenital tract through regular
condom use, although this also remains a distinct possibility.
.......... Two interesting things emerged from these correspondences.
First, under examination, many of these talc free condoms had other
particles on them, such as vegetable starches, silica, mica and
diatomaceous earth. One brand contained numerous lycopodium (club moss)
spores. Spores of the club moss were used as absorbents in surgical
glove donning powders earlier this century, but the practice was
abandoned when it was shown that lycopodium caused granulomas (small
fibrous growths) and peritoneal adhesions (the abdominal organs become
inflamed and begin to stick together) (Arch Pathol, 1933; 16:326-31; J
Cutan Pathol, 1988; 15: 120-3).
Q:A while back a friend of mine brought to my attention an item which
you published on the possible link between condoms and cancer in women
(WDDTY, vol 6 no 2). If this is true it must be the greatest medical
scandal of all time. I would like to kn A:The British "kite mark" is an
assurance of quality control (ie, your condom is unlikely to break or
leak). It does not necessarily ensure that your condom is free from
harmful substances. Your GP should review articles published in the
medical press recently which have concerned themselves with the process
of moulding latex into things such as condoms and surgical gloves a
process which involves the use of talc, cornstarch and other powders.
The truth is that no one knows what risks we may face because of the
long term use of condoms. It has only been in the last few years, as
condom use has increased due to the fear of sexually transmitted
diseases, that it has become an issue.
Talc is used in the manufacture of latex goods both as a lubricant and
to release the product from the mould used in its manufacture. The use
of talc on surgical gloves was virtually eliminated early in the 1990s
since there was evidence that it created inflammation and adhesions in
some surgical patients (Arch Dermatol, 1994; 130: 48-53). Although some
condom manufacturers still use talc as a dry lubricant, others use dry
lubricants such as silicone and cornstarch.
The harmful effects of talc on human tissue were first recorded in the
1930s. Thirty years later there was a reported case of a woman who had a
significant amount of talc in her peritoneal (abdominal) cavity talc
which matched that found on the surface of her husband's condoms
(Lancet, 1963; 1: 1295-6). The authors concluded that talc travelled up
through the fallopian tubes and became implanted in the peritoneal
cavity. They also predicted that talc might contribute to occlusion
(blockage) and sterility. A more ominous series of studies linked talc
to ovarian cancer talc was observed in a number of ovarian and uterine
tumours as well as in ovarian tissue (Lancet, 1979; 2: 349-51; J Ob Gyn
Br Commonwealth, 1971; 78: 266-72) and it has since been confirmed that
talc, either placed on the perineum (or on the surface of underwear,
sanitary towels, diaphragms or condoms), can reach the ovaries via
ascent through the fallopian tubes (Am J Epidem, 1989; 130-394; Ob Gyn,
July 1992). There has been little attention paid to the possibility of
damage to the male urogenital tract through regular condom use, although
this also remains a distinct possibility.
In 1995, Dr Candace Sue Kaspar produced two reports on the possible
adverse effects of talc in condoms (JAMA, 1995; 273: 846-7; JAMA 1995;
274: 1269-70). Many condom manufacturers were quick to get in touch with
Dr Kaspar to point out that they no longer used talc or were phasing out
its use.
Two interesting things emerged from these correspondences. First, under
examination, many of these talc free condoms had other particles on
them, such as vegetable starches, silica, mica and diatomaceous earth.
One brand contained numerous lycopodium (club moss) spores. Spores of
the club moss were used as absorbents in surgical glove donning powders
earlier this century, but the practice was abandoned when it was shown
that lycopodium caused granulomas (small fibrous growths) and peritoneal
adhesions (the abdominal organs become inflamed and begin to stick
together) (Arch Pathol, 1933; 16:326-31; J Cutan Pathol, 1988; 15: 120-3).
Moreover, as Kaspar and colleagues pointed out, lycopodium can be
contaminated with talc, sulphur and/or gypsum. Lycopodium has not been
linked with cancer, but is associated with inflammation of the soft
tissues. There are other problems with what is touted as the world's
safest contraceptive device. Increasingly it is becoming associated with
contact dermatitis in both men and women. In one study 24 per cent of
those who regularly used condoms experienced local swelling and/or
itching during intercourse (Contact Derm, 1989; 20: 360-4). There have
also been reports of allergic reactions to talc substitutes, such as
cornstarch, used in their production (Cutis, 1986; 38: 291-3)...........
In fact, cornstarch has been implicated in hypersensitivity reactions in
patients whose surgeons use gloves dusted with it (Br J Surg, 1976; 63:
864-6) as well as granulomas in various organs throughout the body
......... According to research, talc on condom can cause ovarian
cancer, ovarian/uterine tumors, and uterine abnormalities which can all
lead to miscarriage
