Potentially lifesaving!!

I am so impressed with this app and the Know Your Lemons Campaign as a whole. As a 45 year old woman I’ve been checking my boobs incorrectly my whole adult life. The app guides you through self examination and also tells you what to do when you find something that could be a risk. It’s a very simple app to navigate and is suitable for all ages. I honestly feel that this app will save lives if it hasn’t already.If you are going to install one app today, please make sure it’s this!

I really wanted to love it, but not all cancerous lumps are hard!

Hi, I really wanted to love this app and recommend it to all my friends. I downloaded it and watched the ‘How to self-exam’ video and was really disappointed to hear that they split lumps into 3 groups: hard lumps like lemon seeds, soft lumps like peas and soft lump like beans. The video then classifies hard lumps as cancerous and soft lumps as either lymph nodes or milk lobes. This is really dangerous! Not all cancerous lumps are hard. My cancer was lobular breast cancer, which often doesn’t present as a lump. Mine did present as a lump but is was soft and squishy - more like a blister. I agree that not all lumps are cancer, but if I’d watched this video, I might not have checked it out. Please correct and update your video as I’d love to give you 5 stars! 😊

Never received a notification when it was time to do a breast check. Then all of a sudden I couldn’t login. The pop up screen to enter my passcode didn’t appear. I contacted them via the help/support feature on the app but no one responded. I then contacted them via instagram eventually I got a reply telling me to delete the app and reinstall it. That only worked for one login when I tried again I experienced the same issue. Contacted them again via instagram and got asked the usual questions, ensure that I’m using the latest version which I was. Told to delete the app which I explained I had. Then then sent me a link on how to delete the app (I’m a millennial). I just deleted the app after months of little to no support. Just unfollowed them on instagram. I love the idea of the app but if it doesn’t work then there is no point. On a hunt for replacement app.

Checked my boobs, found a lump, it was cancer. Got the all clear now having had chemo, surgery and radiotherapy. I wouldn’t have felt confident about what I was feeling for if it wasn’t for this app.
