It certainly is possibly this lump could be cancerous at Pumpkin's age, and any growing lump should be checked out by a vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have her seen by a vet tomorrow to have this lump examined and diagnosed so it can be treated as needed. Good luck, I hope this helps!

My dog has a pink wart type of growth on her shoulder but I see a black spot on it and want to know if it needs to be examined.
Any suspicious lumps should be examined by the vet. This lump on Ophelia could be caused by a wart, but it could also be due to a benign tumor or a malignant tumor. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Ophelia seen by a vet on Monday or Tuesday to have this lump examined and diagnosed so it can be treated as needed.

I found what looks like a mass on my dogs. Do you think it’s cancer? I’m really worried..
Thanks for using Boop by Petco! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

My 9 year old dog has a firm white pimple like bump near his groin. Is it cancerous or benign?
Without seeing Jackie in person and doing tests on the lump, there is no way I can say if it's cancerous or benign. In an older dog, there is always a chance a lump could be cancerous. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call today to make him an appointment. Best of luck.

My 9 year old German Shepherd has a small pea sized hard black lump. It doesn't seem to bother him and he is in good shape.... other than being overweight.

Hi I have a 11 year old miniature poodle female. I noticed a a black spot on her nipple that has never been there before. I was wondering if it can be breast cancer?
Thanks for using Boop by Petco! It is possible to know without being able to examine her. However, this could be a benign or malignant growth or even a normal pigmentation change. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign.

Hi I found a black lump on my dogs rear right leg about 3-4 months ago and I took her to the vet and they said it could be cancerous or it could be something as simple as a wart so they said to keep an eye on it and make sure it doesn’t change at all
Thanks for using Boop by Petco! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Maddy evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

My dog a big black lump on the underside of stomach near her privates, is it a tumor?
It may very well be a tumor, but without a physical exam and diagnostics, whether or not it is benign or malignant cannot be determined. You can choose to monitor it at home for rapid growth or change, discharge, bleeding or discomfort then have Pepper seen by your veterinarian or you can schedule an exam right away. Your veterinarian may perform a fine needle aspirate to collect samples for pathology or schedule Pepper for a biopsy procedure to collect a more substantial sample. Treatment options will depend on the results of the exam and aspirate/biopsy.

Is something wrong here? My dog normally has a wilder bump there but it seems to have gotten bigger.
That is concerning, and in a dog Happy's age, that can be caused by something serious like a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed.

my 5 year old golden retriever has bumps or cyst which is transperent and bluish.it has not grown.it is smaller in size.how to take care of him?is it cancerous?
In a middle age dog, there could be a chance a lump is malignant, but it could also be cyst, an abscess, or benign tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd take Caeser to the vet today. Best of luck.

Our 7 year old female Boston Terrier has a black (soft and movable) mole/growth on her face. It has increased in size since we noticed it about 4 or 5 months ago. What could this be? We see a local farm vet and he just said aww it's nothing to worry
This growth on Kyela's face could simply be benign, but there is a chance it could be malignant. This should be checked out by a vet because it's been growing in size. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd give her vet a call tomorrow to make her an appointment. Best of luck, I hope this helps!
