Assuming your product only belongs to one category. You could override the getBreadcrumbPath function in Mage_Catalog_Helper_Data in this way:

if (!$this->_categoryPath) {

   $path = array();
   $category = $this->getCategory();

   if(!$category && $this->getProduct()) {

      $categoryIds = $this->getProduct()->getCategoryIds();
      if (is_array($categoryIds) and count($categoryIds)) 
          $category = Mage::getModel('catalog/category')->load(array_pop($categoryIds));
   }

   if ($category) {
   ...

Untested, but it should work

this will show like breadcrum.

I know this is quite old, but I'd like to share my solution anyway as it doesn't override/clone any core files.

In your custom module add the following to your config.xml:

<config>
    ...
    <frontend>
        <events>
            <catalog_controller_product_init>
                <observers>
                    <breadcrumb_categorypath_product_init>
                        <type>singleton</type>
                        <class><Your Namespace>_<Your Module>_Model_Observer</class>
                        <method>fullBreadcrumbCategoryPath</method>
                    </breadcrumb_categorypath_product_init>
                </observers>
            </catalog_controller_product_init>
        </events>
    </frontend>
</config>

Create an Observer.php in /app/code/local///Model/

Add the following to your Observer.php:

class <Your Namespace>_<Your Module>_Model_Observer {
    public function fullBreadcrumbCategoryPath(Varien_Event_Observer $observer) {
        $current_product = Mage::registry('current_product');

        if( $current_product ) {
            $categories = $current_product->getCategoryCollection()->addAttributeToSelect('name')->setPageSize(1);
            foreach( $categories as $category ) {
                Mage::unregister('current_category');
                Mage::register('current_category', $category);
            }
        }
    }

It would be wiser to rewrite the Mage_Catalog_Helper_Data, as it provides the data on what categories will be added to breadcrumbs.

Assuming you know how to rewrite that helper class, here's what you have to do:

Rewrite the class Mage_Catalog_Helper_Data.
Override getBreadcrumbPath method.

Copy the original method but modify these lines:

// add category path breadcrumb
foreach ($pathIds as $categoryId) {
    if (isset($categories[$categoryId]) && 
        $categories[$categoryId]->getName() &&
        $categoryId != $YOUR_CATEGORY_ID // Notice the extra category check here...
    ) {
        $path['category'.$categoryId] = array(
            'label' => $categories[$categoryId]->getName(),
            'link' => $this->_isCategoryLink($categoryId) ? $categories[$categoryId]->getUrl() : ''
        );
    }
}

Replace $YOUR_CATEGORY_ID variable or set a value for it.

EDIT:

In case you don't know how to do a class rewrite

Open the file Mage_Catalog_Helper_Data.
Find the method getBreadcrumbPath. It starts with something like public function getBreadcrumbPath()

Replace the whole method with this code:

public function getBreadcrumbPath()
{
    if (!$this->_categoryPath) {

        $path = array();
        if ($category = $this->getCategory()) {
            $pathInStore = $category->getPathInStore();
            $pathIds = array_reverse(explode(',', $pathInStore));

            $categories = $category->getParentCategories();

            !$category_ids_to_remove = array(YOUR_CATEGORY_ID_1, YOUR_CATEGORY_ID_2);
            // add category path breadcrumb
            foreach ($pathIds as $categoryId) {
                if (isset($categories[$categoryId]) && 
                    $categories[$categoryId]->getName() &&
                    !in_array($categoryId, $category_ids_to_remove) // Notice the extra category check here...
                ) {
                    $path['category'.$categoryId] = array(
                        'label' => $categories[$categoryId]->getName(),
                        'link' => $this->_isCategoryLink($categoryId) ? $categories[$categoryId]->getUrl() : ''
                    );
                }
            }
        }

        if ($this->getProduct()) {
            $path['product'] = array('label'=>$this->getProduct()->getName());
        }

        $this->_categoryPath = $path;
    }
    return $this->_categoryPath;
}

Replace the text YOUR_CATEGORY_ID to the actual category ID of the category you want to hide. It should work after that.

Please take note that rewrite core classes is extremely not recommended as core files are replaced whenever you update your magento.
