Hello frens,

&amp;#x200B;

I uploaded a [dataset of MRI Scans for brain tumor segmentation](https://www.kaggle.com/andrewmvd/brain-tumor-segmentation-in-mri-brats-2015). It is the training set for the BraTS competition for the years 2018, 2019 and 2020. The data contains MRI scans and expert segmentations for HGG and LGG (high grade and low grade gliomas), as well as survival data. 

It can be used for tumor type classification, tumor segmentation and survival analysis.

Hope it helps,
