Why dont plants suffer from the effects of aging and cancers like mamals do?

So bare with me its been a while since my last biology class. 


If the semi-conservative replication of DNA causes degredation over time which leads less and less acurate copies of DNA strands is attributed with causing the visable effects of aging, and higher occurances of cancers. 

Then how can plants such as redwood trees live for hundreds of years with out simply dying of old age ?

Trees can get cancer, but because of harder cell walls in plants, they can't traverse throughout the "body".

As for old age, technically nothing dies of old age. People die of pneumonia or heart attacks or stroke, which is attributed to old age. Similarly, a long lived tree is more likely to be burned down or struck by lightning or get a deadly fungus.
