Detaljeret beskrivelse
This study aims to determine whether metabolic changes associated with cancer produce distinct alterations in exhaled breath compared with those of healthy individuals. Breath samples will be analyzed using machine learning techniques to identify volatile organic compound (VOC) patterns and develop diagnostic algorithms capable of detecting multiple types of cancer. The long-term goal is to establish a noninvasive, breath-based screening tool that can facilitate the early detection of various cancers.
Additionally, patients and healthy participants who consent to this study may opt in to be contacted in the future to provide additional breath samples.

Diagnosed Malignancies
Participants in this group either have a newly diagnosed, untreated cancer or a pre-existing cancer diagnosis but are not currently receiving anticancer therapy.
Participants with a pre-existing diagnosis must not have received any anticancer treatment within the previous month.
|
This is a noninvasive intervention.
Participants will be asked to provide a breath sample using a disposable mouthpiece equipped with a saliva/moisture trap and a non-rebreathing valve.
Breath samples will be collected through normal, steady exhalation.
The entire breath collection process is expected to take no more than 30 minutes to complete.
