Study Finds Infections May Cause One in Eight New Cancers
Some germs can stay inside the body for a very long time.
These infections may cause irritation called inflammation.
They can also interfere with how cells normally work.
Over time, this can help abnormal cells survive and multiply.
A study says infections may be linked to one in eight new cancers.
H. pylori is linked to stomach cancer.
HPV causes nearly all cervical cancers and is linked to some other cancers.
Hepatitis B and C can lead to liver cancer.
EBV is linked to several cancers, including some lymphomas.
A new study reported that infections may cause one in eight new cancers.
Long-lasting infections can remain in the body for years and contribute to cancer development.
Chronic infections may promote cancer by causing inflammation or disrupting normal cellular processes.
H. pylori is strongly linked to stomach cancer, while HPV is responsible for virtually all cervical cancers.
Chronic hepatitis B and C infections can lead to liver cancer, and EBV is associated with several cancers.
- Who
- The study concerns people who develop cancers associated with persistent infections.
- What
- A study found that infections may cause one in eight new cancers and described several infection-cancer links.
- When
- The article does not specify when the study was conducted or published.
- Where
- The article does not specify a location.
- Why
- Persistent infections may cause inflammation, disrupt normal cellular processes, or enable abnormal cells to survive and multiply.
- Estimated cancer share
- One in eight new cancers may be caused by infections, according to the study title.
- Cancer mechanism
- Persistent infections can cause inflammation, interfere with normal cellular processes, or alter cells.
- H. pylori
- Strongly linked with stomach cancer.
- HPV
- Responsible for virtually all cervical cancers and associated with several other cancers.
- Hepatitis B and C
- Chronic infections can lead to liver cancer.
- EBV
- Associated with nasopharyngeal carcinoma and certain lymphomas.
