Enzyme TherapyEnzymes. You’ve probably heard the word here and there. The fact is that enzymes play
important roles in our body. But, it turns out, they may also play a big role when it comes to
fighting cancer.

It’s obvious that treatments like chemotherapy and radiation, despite being the standard, go-to
treatments for many cancers, have limitations of their own: cancer cells becoming resistant to
treatments like chemotherapy, the multitude of painful, uncomfortable side effects, are just a
few. That’s why new treatments are constantly needed.

Keep reading to learn more about how researchers are leveraging naturally-occurring enzymes
and how these strategies could help you in your cancer treatment journey.

What are enzymes?

What are enzymes?
Enzymes are found naturally in the body, and they play very important roles. At a very basic
level, enzymes function as a catalyst in the body. In other words, they initiate processes in the
body that are needed for daily functioning. Both plants and animals have enzymes to help them
carry out biological functions.

For example, amylase is an enzyme found in our saliva. It initiates a process for breaking
starches into sugars when we eat food. Other examples include lipase (found in the gut) and
trypsin (found in the small intestine).

What is enzyme therapy?

Enzyme therapy, as the name suggests, refers to the use of enzymes to treat cancer or
ameliorate the side effects of cancer treatment.

The most common types of enzymes used in cancer enzyme therapy include proteases
(bromelain, papain, or chymotrypsin). Proteases are a specific type of enzyme that break down
other proteins with the goal of producing more or new proteins.

Unfortunately, it’s still not exactly clear why enzyme therapy is helpful as a potential cancer
treatment and support therapy. Some research suggests that these enzymes lead to the
production of antiproteinases, which some research suggests can have anticancer effects,including helping affect the spreading of tumors and cancer cells around the body (metastasis).

Is enzyme therapy effective for cancer?

 Is enzyme therapy effective for cancer?
While much more research is needed to conclusively say that enzyme therapy is effective,
existing research has produced promising results regarding enzyme therapy’s potential as an
anticancer treatment. Here are a few key findings from studies:

  • Preventing cancer cells from spreading. As mentioned above, certain types of
    enzymes in enzyme therapy could help prevent cancer cells from spreading throughout
    the body.
  • Targeting cancer with nanozymes. Cutting-edge research has explored the use of
    artificially-developed enzymes, called nanozymes, that could work in place of natural
    enzymes. However, limitations such as the low amount of activity these enzymes
    produce need to be overcome first.
  • Boosting the immune system. A lot of new cancer treatments focus less on targeting
    cancer directly and instead supporting the body to help it fight cancer more naturally.
    Some research has explored the possibility of using enzyme therapy to boost the
    immune system. One study explored the enzyme PEG-KYNase, which can help the
    immune system target cells that should not be there, such as cancer cells.
  • Preventing cancer. Some recent research has even explored how enzymes could play
    a role in preventing cancer. Specifically, researchers are looking at how certain enzymes
    could be the target of future drugs to prevent cancer, rather than using enzymes
    themselves to treat cancer.
  • Making immunotherapy more effective. Immunotherapies help boost the body’s
    immune system. However, they don’t always work for everyone. One study found that
    targeting a specific enzyme in the body could help boost the effectiveness of an
  • Treating the side effects of cancer treatments. Enzymes can help replace enzymatic
    activity that’s disrupted by cancer. For example, people with pancreatic cancer may
    benefit from enzyme replacement therapy. These enzymes can help support healthy
    pancreatic activity that may have been disrupted by cancer in the first place.

Is enzyme therapy safe?

Is enzyme therapy safe?
Generally speaking, enzyme therapy is safe, at least based on the available evidence. Nothing
serious has occurred in people who have received enzyme therapy, though there is some
evidence of mild gastrointestinal side effects following enzyme therapy.
