Find out whether you could be at risk for soft tissue sarcoma.
Soft tissue sarcoma is not common, and in most cases the cause of the cancer is unknown. Still, there are certain risk factors to be aware of and warning signs of soft tissue sarcoma to watch out for.
Soft tissue sarcoma is a type of cancer that forms from soft tissues. This includes your muscles, tendons, nerves, and blood vessels. Soft tissues connect and support other tissues in the body.
What are the risk factors for soft tissue sarcoma?
You’ve already been through cancer treatment.
Soft tissue sarcomas may develop in patients who’ve received radiation therapy in the past. They may have received radiation for other cancers, often in the area of the body that needed radiation. “For instance, following breast cancer treatment, where we treat the whole breast after a lumpectomy, women can develop a secondary, radiation-related cancer 7 to 10 years after treatment,” says Richard Bakst, MD, a Radiation Oncologist at The Mount Sinai Hospital. Luckily, this is rare.
You were born with certain genetic conditions.
Family cancer syndromes are disorders that stem from gene defects. You generally inherit these types of gene defects from a parent. As a result of these, you may have a higher risk of certain cancers, including soft tissue sarcomas. Some examples include:
- Li-Fraumeni syndrome
- Gardner syndrome
- Werner syndrome
- Gorlin syndrome
- Tuberous sclerosis.
“Those are genetic syndromes [are] typically diagnosed at a young age,” says Dr. Bakst. "Patients with those genetic syndromes would likely be screened for a number of different cancers, including soft tissue sarcoma."
You’ve had exposure to certain chemicals.
High exposure to dioxin or herbicides that contain phenoxyacetic acid may be a risk factor for soft tissue sarcoma. Studies have linked vinyl chloride (a chemical used in making plastics) and arsenic to liver sarcoma. However, researchers have not been able to prove that they cause soft tissue sarcoma.
“It’s important to keep in mind that soft tissue sarcomas are relatively rare, and that most things you notice on your body are not soft tissue sarcoma,” says Dr. Bakst. “Just be vigilant of changes in your body, and present to a primary care doctor if you are concerned about anything for further workup.”
Dr. Bakst is a board-certified radiation oncologist and assistant professor at The Icahn School of Medicine at The Mount Sinai Hospital.
00:00:00,000 --> 00:00:03,223
00:00:03,223 --> 00:00:05,920
In general we don't know
the cause of soft tissue sarcoma.
00:00:05,920 --> 00:00:09,009
However, there are certain risk factors
associated with developing soft
00:00:09,009 --> 00:00:09,799
00:00:09,799 --> 00:00:15,260
00:00:15,260 --> 00:00:19,364
Soft tissue sarcomas are a type of
cancer that originate in soft tissues of
00:00:19,364 --> 00:00:21,892
the body, but
could also originate in bone.
00:00:21,892 --> 00:00:24,330
And so they occur throughout the body.
00:00:24,330 --> 00:00:28,278
Most soft tissue sarcomas tend to
originate below the waist, but
00:00:28,278 --> 00:00:31,383
they could really arise
from any of those origins.
00:00:31,383 --> 00:00:35,550
If you've had prior cancer treatment for
an unrelated cancer, including chemo
00:00:35,550 --> 00:00:40,190
therapy or radiation therapy, you could
be at increased risk for sarcoma.
00:00:40,190 --> 00:00:42,900
So for instance,
following breast cancer treatment, and
00:00:42,900 --> 00:00:47,265
where we treat the whole breast after a
lumpectomy, women can develop a secondary
00:00:47,265 --> 00:00:50,960
radiation-related cancer seven
to ten years after treatment.
00:00:50,960 --> 00:00:55,019
This is exceedingly rare, probably
occurring in less than 1% of patients.
00:00:55,019 --> 00:00:58,780
However, those secondary cancers
may be a soft tissue sarcoma.
00:00:58,780 --> 00:01:02,220
Carcinogen exposures have always
been hypothesized as a cause, but
00:01:02,220 --> 00:01:04,030
there's no clear link.
00:01:04,030 --> 00:01:08,130
And also certain genetic backgrounds
make you predisposed to cancer types,
00:01:08,130 --> 00:01:10,120
including soft tissue sarcoma.
00:01:10,120 --> 00:01:12,480
Some examples include
00:01:12,480 --> 00:01:15,100
which is associated with a number
of different solid tumors,
00:01:15,100 --> 00:01:18,670
including soft tissue sarcoma and
00:01:18,670 --> 00:01:22,140
Those are genetic syndromes which
are relatively uncommon, thankfully.
00:01:22,140 --> 00:01:24,848
However, they are typically
diagnosed at a young age.
00:01:24,848 --> 00:01:28,246
And so patients with those genetic
syndromes would likely be screened for
00:01:28,246 --> 00:01:31,750
a number of different cancers,
including soft tissue sarcoma.
00:01:31,750 --> 00:01:35,152
So it's important to keep in mind that
soft tissue sarcomas are relatively rare
00:01:35,152 --> 00:01:38,265
and that most things you notice on
your body are not soft tissue sarcoma.
00:01:38,265 --> 00:01:42,214
Just be vigilant of changes in your body,
and present to your primary care
00:01:42,214 --> 00:01:45,668
doctor if you are concerned about
anything for further work up.
