# Cancer Risk vs NCCN Guidelines®

The clearest difference is price: NCCN Guidelines® at Free against Cancer Risk's $1.99. NCCN Guidelines® also leads on rating (3.6 vs 2.0) and ratings volume (24 vs 1). Cancer Risk's advantage is review sentiment (33% vs 13%). On update cadence, ads, in-app purchases and device support there is nothing between them.

NCCN Guidelines® is free to download; Cancer Risk costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

NCCN Guidelines® holds the better App Store score, 3.6 against 2.0. That said, the two scores are not equally well evidenced: NCCN Guidelines® has 24 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Cancer Risk's written reviews are positive against 13% of NCCN Guidelines®'s, so the app with the better star average is not the one people write more warmly about.

Cancer Risk ships an update every 3 months, NCCN Guidelines® every 2 months. The most recent releases landed on November 11, 2026 and November 1, 2026 respectively.
