ALK-positive lung cancer is rare, which makes the diagnosis all the more confusing — for you and for the people around you. We are a Belgian patient association, founded by patients and their families. We connect you with specialists who know this mutation, with reliable information, and with others who understand what you are going through.
An ALK-positive diagnosis can feel overwhelming. ALK-positive lung cancer is treatable, and targeted therapies have substantially improved treatment outcomes. Treatment options depend on each person's situation, and research continues to advance.
~4%
of all lung cancers are caused by the ALK translocation
~65%
of ALK+ patients have never smoked
~50%
are under 50 years old at the time of diagnosis
2,500+
members across 50 countries in the worldwide ALK+ network
“ALK-positive” refers to an alteration in the ALK gene (Anaplastic Lymphoma Kinase) which results in an uncontrolled multiplication of certain cells which causes a particular type of lung cancer.
Anyone with lungs is at risk. This rare cancer can only be diagnosed through molecular testing.

«From then on, I have been taking TKIs and the cancer is stable.»
