About Leo Cancer Care
Cancer is one of the biggest killers that we face today with 1 in 5 people diagnosed at some point in their life, it is something that affects us all. 50% of all patients diagnosed with cancer should receive Radiation Therapy as part of their treatment but due to the cost, size and complexity of current technology, the number that do is around half of that.
Current Radiation Therapy is delivered with a patient lying supine on a table while a large machine is rotated around them delivering radiation from different angles to kill the tumour. Lying on a table, many patients report that they feel like a passenger in their treatment feeling vulnerable through the entire process. Leo Cancer Care was founded with one clear goal, to bring a more human way to treat cancer and empower patients to face treatment on their feet.
We are looking for an enthusiastic individual to complement our passionate team in their mission to revolutionizing cancer treatment. You can be part of a world class team, developing the treatments of tomorrow.
Leo Cancer Care is helping make changes in Radiation Therapy by shifting to upright patient positioning, imaging and treatment. We do what we do to find a better way, a better way to treat cancer and create a paradigm shift in radiation therapy to benefit all. We will do this by improving the accessibility and medicine in cancer care globally, making cancer treatment a more human experience for all.
Working in radiotherapy not only will you be driving change for the greater good, but you'll be working on products that span a large field of different disciplines.
Leo Cancer Care is dedicated to fostering a diverse and inclusive workplace environment. We embrace and celebrate the unique backgrounds, experiences, and perspectives of all individuals.
