Cancer Chatbot


Jonno Boyer-Dry is a 30-year old cancer survivor who was diagnosed with Stage IV Hodgkin’s Lymphoma. He conducted massive research to get the resources that will be useful for cancer patients, caregivers, and family members to start with. The variety of such websites makes it hard to find valued information amongst a noise. There was no centralized place to find the resources. Then the first version of the Cancer Chatbot by CSource appeared.

We cannot imagine what the patients or family members are dealing with. But we can help, inform and support them, so that what we did. We rebuilt a chatbot for Jonno and his wife, Allison Boyer-Dry’s.


Cancer Chatbot leads users through different resources and gives advice based on Jonno’s own experience. Our goal was to make the chatbot well-structured and user-friendly. We used Chatfuel as a chatbot building platform and Facebook Messenger as an environment.

One of the most important things Cancer Chatbot possesses is the important resources it comprises. Here are some of them:

Resources of the Cancer Chatbot

Now users can always have them on hand. Besides, Cancer Chatbot includes helpful tips and recommendations for those who are somehow related to the disease.

You can Leave a Feedback right in the bot. Use the button to share the important resources, or to share good words with the founder of the chatbot.

What We Created

Our main challenge was to optimize a Google Site Search among the different resources. As the websites are different in their design and structure, we needed to make them display properly.


Site search is one of the most important features of the chatbot. In the case of its improper optimization, the bot would easily lose its value.

Our goal was to improve and make the site search more targeted. To get an answer to a question, users can choose certain themes in the form of quick replies or simply type their queries. Some of the search queries are already set up in the chatbot for user convenience the form of the answers is handy and easy to perceive.

Users see all the variants of answers in the form of a gallery. The cards comprise an image, heading, subtitle and “Read more” button. It redirects users to the source of an answer. Users can also subscribe to their search result and get updates on a certain theme.

Chatbots for Healthcare

The previous version of the Cancer Chatbot was very inconvenient to use as its structure was circled. There was no option to go back to the previous step or the main menu.

We connected the cards by Postback buttons and Quick Reply buttons. Under some of the Postback buttons hidden the links so you can to go to the web view by a click. Setting up AI rules lets to find a block by writing some word in the chatbot.


The initial version of the bot was chaotic and not user-friendly. Our main aim was to reorganize the structure of the chatbot and solve such issues as UX-dead ends and closed cycles. Initial flow was too difficult to follow. Users used to get lost in the mass of texts and resources and just leave the chatbot. The updated chatbot allows users to skip from one section to another, perceive information with no difficulties and never be left with dead ends. Also, the chatbot provides users with alternatives for further steps that might be interesting. Bot’s considering the user’s current location, point, and place.
