Inflammation is your body’s natural response to infection or injury. In normal circumstances, inflammation eliminates foreign invaders (bacteria or viruses) and damaged cells to heal wounds within hours or days. However, this life-saving process can also be harmful. Chronic inflammation is linked to more than 50 per cent of all deaths worldwide and one in five cancers.
When does inflammation become a problem?
While some inflammation is normal, too much can be harmful to your health. Chronic (long-lasting) or excessive inflammation is linked to many serious conditions.
Harmful inflammation can occur when
- The inflammatory response is too strong
- It lasts longer than it should
- Your body can’t turn it off properly
Common causes of chronic inflammation include
- Long-term infections
- Ongoing production of harmful substances in the body (often seen in obesity or type 2 diabetes)
- Autoimmune diseases like lupus, where the immune system mistakenly attacks healthy tissue
Understanding and managing inflammation is crucial for your overall health.
How does inflammation contribute to cancer?
Scientists have discovered several ways that chronic inflammation may fuel cancer growth and spread:
- DNA damage: Long-term inflammation can harm the genetic material (DNA) in cells, affecting how they grow and divide. This damage may lead to cancer.
- Altered cell signals: Inflammatory immune cells can release substances that change how developing tumour cells behave.
- Cancer spread: Inflammation brings cells to cancer sites that may help the cancer spread to other parts of the body.
Certain chronic inflammatory conditions may increase cancer risk including
- Pancreatitis (inflammation of the pancreas) may increase risk of pancreatic cancer
- Crohn’s disease (intestinal inflammation) may raise risk of intestinal cancers
Some chronic infections that cause inflammation are also linked to cancer
- Helicobacter pylori bacterial infection can lead to stomach cancer
- Hepatitis B or C virus infections may cause liver cancer
Understanding these connections helps researchers develop new ways to prevent and treat cancer. If you have a history of chronic inflammation or infection, talk to your doctor about your cancer risk and prevention strategies.
What causes chronic inflammation?
Chronic inflammation can be triggered by various factors in our lifestyle and environment. Common causes include
- Lifestyle choices: smoking, excessive alcohol consumption, obesity
- Health conditions: long-lasting infections, autoimmune diseases (where the body’s immune system attacks healthy cells)
- Environmental factors: exposure to chemical irritants
Understanding these causes is the first step in managing and preventing chronic inflammation.
If you’re concerned about chronic inflammation, talk to your healthcare provider. They can help you identify potential causes and develop a plan to reduce inflammation in your body.
Inflammation and cancer research at Hudson Institute
Ongoing research is shedding light on how long-lasting inflammation may contribute to certain aggressive cancers, including those affecting the lungs and stomach. Our scientists are working to uncover how the immune system’s response to inflammation might play a role in cancer development. By understanding this connection, we aim to
- Reveal how inflammation affects tumour growth
- Develop new medications that target inflammation to fight cancer
- Improve treatments for cancer patients.
This research brings hope for better ways to prevent and treat cancer.
Inflammation and cancer research projects underway
Boosting IL-18 to defeat cancer
The immune system has the ability to defeat cancer, but often needs to be turned up to work effectively. One immune protein that can work well is called IL-18, but is not very active in most types of cancer. Professor Master’s team has designed a product that increases IL-18 activity and is looking to turn this into an anti-cancer therapy.

Closing in on ovarian cancer therapy
New treatment Discovered by Prof Hertzog’s team, interferon epsilon is found in the reproductive tract of women where it activates the local innate immune response that controls inflammation. This process is important in protect us from infections and also the development and spread of cancer. The team is developing a novel candidate for the treatment of ovarian cancer with a commercial partner.

RNA therapeutics for immunotherapy
Molecular studies. Cancer cells are good at hiding from the immune system. However, if immune cells engage with tumours, the immune system can learn to recognise and remove every single cancer cell. Associate Professor Gantier is investigating how RNA therapeutics, similar to those used in mRNA vaccines, can be used to reignite immune activity in tumour cells to drive systemic anti-tumoral responses. This work has immense potential for the treatment many different cancers, including leukaemia.

Inflammation in cancer cells
Cancer treatments. Associate Professor Gantier is studying how DNA damage initiates inflammatory responses that build resistance against chemotherapy and radiotherapy. This collaborative work with an industry partner, has the potential to revolutionise the efficacy of front-line treatments such as radiotherapy against multiple cancers.

Immune responses that dictate metastatic spread in breast cancer
Molecular studies. The mechanisms that regulate the process of metastases of breast cancer cells to other organs such as the lungs and bone are regulated by the process of inflammation which brings specialist immune cells into proximity to eliminate the metastatic tumour cells. Professor Hertzog’s focus is on the molecules that block the metastatic process and stimulate the immune response in regulating this process.

A new therapeutic target for Helicobacter pylori-induced stomach cancer
Therapeutic target Infection by the bacterium, H. pylori, is a major factor in the development of stomach cancer. Professor Ferrero’s group showed that stomach tissues produce a molecule that reduces the inflammatory changes associated with cancer induced by H. pylori infection. This molecule may be targeted in therapeutic strategies to treat inflammation-induced cancer.

Bacterial vesicles impact host cell functions and modulate inflammation
Molecular studies This project is investigating how bacteria use membrane vesicles to transport molecules into host cells and communicate with these cells. The fundamental insights gained from this work are relevant to the use of bacterial vesicles in vaccines, as well as in gene therapy and gene editing applications. The research will also increase the understanding of how bacteria modulate inflammatory responses during infection.

Illuminating the roles of STAT3 in health and disease
Molecular studies. The STAT gene family is essential for the transmission of chemical signals in cells. One member of this family, STAT3, is essential for life and unregulated changes to its activity result in disease including cancer and immune disorders. Dr Dan Gough’s team uses pre-clinical models, mass-spectrometry, structural biology and biochemistry to investigate the way that STAT3 drives disease and identify new therapies.
