what are really early signs of bone cancer in leg?

The most common form of primary bone cancer is called osteosarcoma, but primary bone cancer is very uncommon. It's also unlikely that you'd notice it early.

The first symptom my grandad had was pneumonia, when it had spread from his spine to his lungs. He was told he had a herniated spinal disc for several weeks before they eventually diagnosed stage four osteosarcoma.

Any cancer is unlikely to produce any obvious symptoms in the early stages.

If it had got to a point where it was producing symptoms, it would be advanced in some way or another. Any pain would be constant.

Many people as me what to look for to tell if their dogs have cancer. Well, I must confess it is a tough question since there are so many cancers, and they all can present a little differently. I thought I should give you a little summary of some of the biggies. First, statistically, cancer TENDS to affect older dogs. So, more lumps and bumps on a young dog are benign than cancerous. One hallmark of a cancer is it worsens over time. Cancers you can see usually get bigger. A growth that stays very small for years is not likely to be a true cancer. Again, this is on average and is not a guarantee. Some cancers are visible, while others are internal. The visible ones can be blackish (melanomas), purplish (hemangiosarcomas), fleshy, inflamed and red (histiocytomas), look like a non-healing open sore (squamous cell carcinomas), be firm, hard and deeply attached (fibrosarcomas), or have any appearance (mast cell tumor, the great imitator). The internal ones are invisible, so we have to look for overall signs in the dog. When they are far along, cancers usually cause weight loss (cancer cachexia) without an obvious external reason. They often will cause less appetite. Many times dog owners will tell me they think their dog got tired of his or her food. They can cause low energy, where the dog will just lay around a lot. Internal cancer signs also depend on where the cancer is happening. For example, a bone tumor (osteosarcoma) might cause a limp, or a bladder tumor (transitional cell carcinoma) might cause straining to urinate, blood in urine, or urinating small amounts frequently. A tumor found in the wall of the stomach might cause vomiting, and in the intestine, diarrhea. Some cancers cause internal bleeding, like hemangiosarcoma of the spleen. This bleeding causes sudden weakness and wobbly legs. A nasal tumor like a squamous cell carcinoma might cause discharge or bleeding from a nostril, or sneezing that won’t go away. Lung cancers (bronchial adenocarcima) or tumors of the heart can cause coughing. Lumps in the breast with discharge from teats could be mammary carcinomas. The good news is, not all of these signs point to cancer. Lots of other things can cause each and every one of these signs. The important thing to remember is to get it checked out by someone who knows what they are doing. If we are dealing with cancer, moving early is the way to go. Best to all,

Cancer can start in the bones, the most common type of primary bone cancers is osteosarcoma. Primary bone cancer is very rare. But, symptoms include pain, mobility issues, and swelling in the area there is cancer, often accompanied by weight loss, fever, night sweats, tiredness. The severity of this really depends on a lot of things, from the size of the tumor to the age of the person, so it feels different for different people. You may develop a limp if the cancer is in a bone in your leg.

The early sign is that you have cancer in another part of your body. Cancer does not start in the bones, it starts somewhere else and when that has gotten really bad it spreads to your bones. So unless you have already been diagnosed with advanced cancer, don't sweat it.

Many bone cancer symptoms can also be caused by conditions such as arthritis, osteoporosis or injury. If you’re experiencing one or more of these symptoms, you should discuss them with your doctor in order to identify the cause and receive the correct treatment, if necessary.

My cousin has osterosarcoma and she did not notice anything until there was suddenly a large swelling in her knee that was extremely painful. She had to be on crutches for several weeks before the doctors could figure out what it was.

She said the pain was always worse at night.
