I'm not sure this is a "medical breakthrough" as described in the PR
article released by Dr. Rath below, but it is possible some of these
supplements could help. I hadn't heard of lysine and proline before
today!

Nutritional Research Company Halts Cancer Metastasis Using Natural
Substances

Vitamin C, L-lysine, L-proline, and Green Tea Combination
Prevents Spread of Cancer

SANTA CLARA, Calif., March 7 /PRNewswire/ -- A medical
breakthrough made by Dr. Matthias Rath provides new evidence that the
invasion and spread of cancerous cells can be inhibited by the use of
specific nutrients. Dr. Rathwill deliver his findings during two
presentations in Orange County: onSaturday, March 9th at 9:30 AM at
the Anaheim Convention Center, Room 205-A;and during a free public
seminar at the Irvine Marriott Hotel near the JohnWayne Airport on
Sunday, March 10th at 3:30 PM. The Saturday presentation is
a part of the Natural Products Expo West and open to trade show
attendees andthe media. The Sunday presentation, also open to the
media, is Dr. Rath'sonly public seminar in southern California. Dr.
Rath will also be hosting amedia briefing on Friday, March 8th at
9:30 AM at the Anaheim Hilton in theOceanside Room.
Dr. Rath is the noted physician and research scientist who
connected vitamin deficiency to cardiovascular disease. His most
recent medical breakthrough identifies natural substances that are
successful in blocking the invasion and spread of cancer cells.
"These remarkable findings have profound implications for cancer
treatment as it exists today," said Dr. Rath, founder of the
international nutritional research company Matthias Rath, Inc. "We
have discovered that the spread of cancer can be inhibited naturally
using specific nutrients, including vitamin C and L-lysine. These
nutrients support connective tissue integrity and control the harmful
enzymatic activity that allows the metastasis of cancerous cells."
Ninety percent of all cancer fatalities result from metastasis,
the invasion and spread of cancerous cells to other parts of the
body. To facilitate their spread, cancer cells secrete enzymes that
degrade surrounding connective tissue. It is this enzymatic activity
that scientists at the Matthias Rath, Inc. research facility set out
to understand and control.
Their experiments involved the use of cancer cells, nutrients, and
collagenous membranes. Various types of cancer cells were combined
with nutritive agents, while others were not. In each instance,
cancer cells not combined with nutritive agents were able to pass
easily through the collagen membrane, whereas cancer cells combined
with various nutritive agents were unable to pass through the
collagen membrane.
Scientists noted that the most powerful and effective nutrient
combination for inhibiting the spread of cancer cells contained
vitamin C, L-lysine, L-proline, and a polyphenol fraction of green
tea. "The results of these experiments confirm that many cancers can
be treated with the use of nutrients," said Dr. Rath. "This paves
the way for a new approach to cancer treatment without the
devastating effects of chemotherapy and radiation. This
is an exciting discovery for cancer patients and physicians alike."
In his book Cancer, Dr. Rath presents the scientific
documentation of his approach to controlling cancer and other
diseases using natural substances such as vitamin C and L-lysine,
nutrients whose therapeutic properties have been the subject of
intensive research at Matthias Rath, Inc.
Dr. Rath and his company are committed to conducting innovative
research and developing natural health therapies that help people
lead longer, healthier lives.
Dr. Rath will be available for media interviews for a limited
time prior to the public seminar.

About Matthias Rath, M.D.
Matthias Rath, M.D. is the noted physician and research scientist
who made the groundbreaking discovery proving the connection between
vitamin deficiency and cardiovascular disease. Dr. Rath introduced
Cellular Health(TM), the new understanding that optimal nutrition for
the body's cells is necessary for optimal health.
Dr. Rath founded the international research company Matthias
Rath, Inc., which has facilities in the Netherlands, Germany,
England, France, and the United States. Previously, he served as the
first Director of Cardiovascular Research at the Linus Pauling
Institute in California. Dr. Rath pioneered clinical research by
documenting the natural reversal of atherosclerosis (thickening and
hardening of arterial walls) using a specifically developed
vitamin formula. His medical breakthrough was awarded a U.S. patent
for the "prevention and treatment of cardiovascular disease."

Not sure of the relationship between "L-proline" and the substance
studied in the abstract below (may not be the same)! But apparently
L-proline and L-lysine are readily available supplements

High anticancer efficacy of L-proline-m-bis (2-chloroethyl) amino-L-
phenylalanyl-L-norvaline ethyl ester hydrochloride (MF13) in vivo.

The anticancer efficacy of the new anticancer tripeptide, L-proline-m-
bis (2-chloroethyl) amino-L-phenylalanyl-L-norvaline ethyl ester
hydrochloride (MF13), was investigated in mice. MF13 showed a
therapeutic effect in liquid tumors and induced complete remission
even in late stage malignancies. MF13 also inhibited human colon
cancer growth in nude mice by more than 85% (volume, p<0.001). It
acted in a dose-dependent manner and induced a complete regression of
tumor in 20% of the mice when the initial dose was high (15 mg/kg,
i.p.). Human melanoma exhibited a response to MF13 similar to colon
cancer. Activity of MF13 in murine hepatoma in vivo was stronger than
its precursor m-sarcolysin (p<0.001). Tumor cells in peritoneal
cavities of the MF13 treated (s.c.) mice underwent an irreversible
apoptosis. Side effects of MF13 were the transient depression of
hemopoiesis and loss of body weight, which vanished within 9-10 days.
LD50 of MF13 of a single i.p. injection was 27 mg/kg (94 mg/m2), 11
times higher than the therapeutic dose of a single injection.
