Looking for help. I've used castor oil on a previous dog's breast lump and although it pulled out the tumor (the size of a baseball) the healing was slow and the large opening never closed up. Even with turmeric, cayenne pepper and any other remedies I could find, she died of sepsis 6 months later. I now have another dog that started with a quarter size lump. This is the second time it's developed. The first time I applied the castor oil, the lump expanded and burst and healing went well. I've been applying castor oil for months to the new lump, a pad consistently in place, sometimes with heat, mostly without. This time the lump although looked like it would expand and burst, instead elongated from the body and stayed that way. Yesterday while changing the pad, I noticed the lump has now doubled in size, closer to the body, hot to the touch and my dog won't let me feel it. I'm not sure if things are getting better or worse and whether a visit to the vet is finally in order. Thanks for reading, all advice is greatly appreciated.

Hello. My dog has an aggressive fibrosarcoma tumor on his front leg. This is the second time, and unfortunately cannot be removed again due to location and not enough skin. I tried the castor oil each night for a week. Yesterday after taking the wrapping off, it bled for a little bit but his entire leg is now swollen. He's favoring it a lot today and won't stop licking at it. I'm not sure what this means or if there's any other remedy I can do. Please help!

My pit terrier mix has a soft pliable, black tumor on leg. Was told I could use castor oil . I got grocery sore brand. Used it along with warm water compresses. The next morning it was bleeding some. I put tumeric in food and cleaned it with Apple Cider Vinegar and then put coconut oil.on it. Should I continue with this? Trying to shrink before removal.Thank you.

Since applying castor oil for a week to my cats fatty tumor it has opened and looks painful. It is under her arm and is causing the leg to swell hugely. Is this normal? should I continue applying castor oil since it is open? She has a cluster of smaller ones too. I tried adding turmeric to her food and she refused it. Please help.

Did you get any response on the burst cyst and castor oil? I was putting castor oil on a large cyst / lump on the back of my dog's neck every day for about 2 weeks. All of a sudden it grew larger and got hard as a rock. It now has burst slightly. Any idea on what to do? What happened with your pet?
