A. Lumps in older cats can potentially be cancerous. So I recommend having your vet get a sample of this swelling and sending it off for analysis so that you know what this is and can treat it appropriately. This is the only way you will know for sure what your cat has when it comes to lumps and masses. If you have the option to go even further it may also be advised to get a radiograph of the hip to check for signs of arthritis that could explain the decreased mobility, especially if the analysis comes back as benign and not cancerous at all. The best news to hope for here is that it is a benign mass and there is just arthritis or degenerative joint disease in the hip area that can be managed with medical therapy.
