Other than "The Cancer Proteome Atlas (TCPA)" (https://tcpaportal.org/tcpa/index.html), which other cancer-based databases/tools can be used to associate a list of genes to identify different types of cancer.
I am not sure what you meant by identifying different types of cancer, but to associate various genes that are either upregulated/downregulated and even compare different mutations, you can have a look at https://www.cbioportal.org/
Hi Pushkal Sinduvadi Ramesh , thank you for your reply. I meant from the list of genes I have obtained, I would like to find our which specific cancer type I can relate them to. I hope this makes more sense now.
you could also utilize online text mining tools such as BEST (Biomedical Entity Search Tool) which is free and also allows you to categorize information (e.g. gene-disease relations, etc.) found inside publications (from the major databases) while allowing you to visualize the relation networks between biomedical entities (genes, proteins, mRNAs, miRNAs, drugs, disease, etc.).
The server is a bit "laggy" these days but if it works for you you can also have access directly to the abstracts of the publications from which the information that you need was retrieved.
