My dog has many mast cell tumors. What are her best treatment options?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! I am sorry to hear that Fudge has a mast cell tumor. There are a few options that I typically recommend for a natural means of treating mast cell tumors. The first is called Oral Neoplasene. This is a liquid type medication that is derived from the bloodroot plant that is used to treat cancer in dogs. The dosging for this product is based on body weight and is usually given prior to feeding two times per day. The second natural remedy I recommend is called Max's Formula. This is a blend of herbs that treats tumors in dogs, cats and horses. It is a blend of eight different herbs that have been carefully chosen to treat tumors. There is a bulk powder you can buy and also capsules. The third product is called Stasis Breaker. Like Max's formula, this also is used to treat tumors in dogs, cats and horses. This is meant to go after the root cause of the tumor. As with any alternative medicine, there is a chance that these products will not work at all. However, if deemed safe, which all 3 of these are safe to use, there is no harm in giving any of these to Fudge. You can order these 3 products online quite easily. I hope this helps! Please let me know if you have any other questions or concerns.

If they are mast cell tumors that is cancer and she needs chemotherapy. What you are already doing is OK but it's not going to "cure" the cancer. Were the removed masses sent to a lab for histopathology? You need to know what they are before you can decided how to treat it.

I’m sorry to hear about Tsunami’s diagnosis. MCTs are quite common in dogs, and unfortunately due to the cell distribution around the primary tumor, incomplete margins are common. If you want to be confident you’re pursuing the best options for the best prognosis, I recommend asking your vet for an oncologist referral. A veterinary oncologist will be the best specialist to be able to present all the options and their given pros & cons, and they have access to chemo medications that most primary vets don’t carry. If you choose not to pursue referral, then I recommend reaching out to your vet again to discuss the next step. If this were my case, I would probably recommend sampling Tsunami’s lymph nodes with a needle to look for evidence of regional metastasis, and based on those findings discuss if a second surgery is appropriate. Hope this helps!

I understand wanting alternative therapy but with a mast cell tumor I do recommend surgery as that can often cure dogs with a localized mast cell tumor. My dog had several and they never returned after surgery. As far as light therapy it is not recommended. The light can speeed up the cell metabolism and in theory cause the cancer cells to divide and spread faster. I use cold laser light therapy in my practice and it is contraindicated to use it around any areas that may be cancerous. Yes, continue with the supplements. If they did a needle aspirate they may be able to grade the tumor to see how aggressive it is. Some mast cell tumors are slow growing and may not need surgical removal. If it’s an aggressive tumor then please consider surgical removal. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Samm.

Mast cell tumor survival rate is entirely dependent on the stage of the mast cell and the mitosis index (seen histologically). So this is a bit more involved than you were likely anticipating it to be. So if Lady has not had a biopsy to gather this information already then there is no way of determining her survival rate unfortunately. The best prognosis is a grade 2 MCt with a mitosis index of <5 at 70 months. The worse was a grade 2 MCT with mitotic index >5 and a survival time of 5 months. Another study suggests that for high grade tumors (MCT grade 2 and above) the mean survival time is <4 months and for low grade tumors (MCT grade 1) the mean survival time is >2 hrs. I hope this helps and feel free to post your question again once you have the necessary information of grading and mitotic index so we can tell you specifically what your pets cancer survival rate is. I am sorry Lady does have mast cell cancer and I hope that you can keep her comfortable for the time being. Best wishes and take care.

Hello, thank you for your question about Zeus. If the lumps/masses were removed with relatively good margins, meaning that your veterinarian was fairly confident they removed all portions of the tumor, and the mast cell tumor was low grade no additional treatment is required other than close monitoring for recurrence in these areas. Although not as common with low grade mast cell tumors, you could elect to look for any evidence of metastasis, or travel of the tumors. This would likely include chest x-rays and an abdominal ultrasound. However, I believe it is also appropriate to continue monitoring Zeus. Hope this helps, good luck!

If you want additional treatments, I would recommend that you discuss referral with your vet to a veterinary oncologist. This question isn't an easy one to answer since it depends on the type, location, current health, potential for spread, etc.
