Tuberculosis (TB) Infection Increases Lung Cancer Risk

It seems like people with tuberculosis (TB) are not only have to face with persistent cough and shortness of breath. A recent study has shown that the TB infection may increase the risk of lung cancer.

The allegation of a link between tuberculosis (TB) and lung cancer actually has long been the subject among the experts. However, there is no single study that proves how the two are closely related.

Recently, researches from the China Medical University managed to prove it after making observations to 700,000 Chinese people, where 4,480 of them were diagnosed with TB between the years 1998-2000. All the participants are observed its development until the time span between the years of 2001-2007.

The results indicated that people who are diagnosed with TB had a 11 times greater risk of lung cancer than healthy participants. “The incidence rate among TB patients is 26.3 per 10,000 person-years, and for those without TB is 2.41 per 10,000 person-years,” said one of the researchers, Sung, from China Medical University.

Sung also found that former tuberculosis patients were at increased risk for other potentially-fatal chronic lung diseases. The scale of the increase came as a surprise to the clinic doctors.

This research has not succeeded in ensuring what factors causes the two are closely related. But at least, these findings strengthen the notion of experts indeed there is a link between TB and lung cancer.

This result was published in the journal of Thoracic Oncology.
