The key features of this app are the Brock and Herder risk prediction and volume doubling time (VDT) calculators that are recommended by British Thoracic Society (BTS) to assist in the diagnosis and management of pulmonary nodules. In the calculators we’ve included associated recommendations from the BTS on patient management. This app has been produced by Cancer Research UK in collaboration with BTS to give clinicians quick and easy access to the calculators and the BTS guidelines for the investigation and management of pulmonary nodules. It includes the four management algorithms that appear in the full guideline document and summarise key parts of the guidelines. These calculators and management algorithms should be used in conjunction with the full BTS Guidelines published in 2015 (Thorax 70, Supplement 2). This app is designed as a tool for clinicians. If you are a patient concerned about your lung health or scan results, you should speak to your doctor or GP. You can also have a look at Cancer Research UK’s patient information website and talk to our cancer information nurses online or by phone.

Verdict

The call

The clearest difference is review sentiment: Thoracic Lymph Node Map at 100% against Pulmonary Nodule Risk's 67%. Thoracic Lymph Node Map also leads on ratings volume (25 vs 2). Pulmonary Nodule Risk's advantage is update cadence (every 10 days vs every 7 months) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Pulmonary Nodule Risk holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Thoracic Lymph Node Map has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Thoracic Lymph Node Map's written reviews are positive against 67% of Pulmonary Nodule Risk's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Thoracic Lymph Node Map ships an update every 7 months, Pulmonary Nodule Risk every 10 days. The most recent releases landed on October 14, 2026 and October 9, 2026 respectively.
