Several types of breast cancer

Mathilde Regnault
There are two main groups of lung cancer.

Small cell lung cancers (SCLC), which are closely linked to tobacco use. These account for 15% of all lung cancers.

Non-small cell lung cancers (NSCLC): these account for more than 80% of all lung cancers. They include the following:

  • adenocarcinoma, currently accounting for 60% of cases
  • epidermoid carcinoma, accounting for 30% of cases
  • large cell carcinoma, which are more rare

Treatment of these tumors is very different and must be tailored to suit each patient.
